1.8) SCHOLAR’S CRITICISM OF THE FINITE ELEMENT METHOD (FEM) THEORY UNDER ENGINEERING AND TECHNOLOGY

The Finite Element Method (FEM), despite its widespread adoption and success in engineering and technology, has faced several scholarly criticisms that highlight its limitations, challenges, and areas for improvement. These criticisms, originating from both early and contemporary analyses, point to issues such as computational complexity, accuracy, assumptions, and application constraints.

One of the earliest criticisms of FEM was its high computational cost. During its development in the mid-20th century, computational resources were limited, and the method required significant processing power to solve large-scale problems (Zienkiewicz & Taylor, 2000). Although modern advancements in computing have mitigated this issue to some extent, FEM remains computationally intensive, particularly for complex and multidimensional problems. High-fidelity models often require powerful hardware, which can be prohibitively expensive for smaller organizations or individual researchers (Bathe, 1996). This limitation persists even today, as simulations involving millions of elements can demand substantial computational resources, making real-time analysis challenging.

Another area of criticism is the inherent approximation in FEM solutions. By discretizing a continuous domain into finite elements, FEM introduces errors associated with mesh quality and element shape (Cook et al., 2002). These errors, often referred to as discretization errors, can lead to inaccurate results if the mesh is not sufficiently refined. However, refining the mesh increases the computational burden, creating a trade-off between accuracy and efficiency. Scholars have also noted that poor meshing strategies or element selection can lead to numerical instability, especially in nonlinear or dynamic simulations (Reddy, 1993). The accuracy of FEM also heavily depends on the boundary conditions and material properties, which must be precisely defined. In practical applications, uncertainties in these inputs can significantly affect the reliability of the results.

FEM has also been criticized for its reliance on idealized assumptions about material behavior and structural conditions. For instance, the method often assumes linear elastic behavior in materials, which may not be valid for certain applications, such as in the modeling of biological tissues or highly nonlinear systems (Jin, 2002). While nonlinear FEM techniques exist, they are computationally more demanding and require advanced expertise to implement. Additionally, FEM struggles to capture discontinuities such as cracks or fractures effectively, necessitating the integration of supplementary methods like extended FEM (XFEM), which increases the complexity of the analysis (Belytschko et al., 1996).

The method’s applicability to multiphysics problems, while expanding, has been another source of critique. FEM often requires coupling with other numerical methods, such as the finite difference method (FDM) or boundary element method (BEM), to address problems involving multiple physical phenomena, such as fluid-structure interaction or thermal-mechanical coupling. These integrations can be challenging to implement and may introduce compatibility issues, further complicating the modeling process (Reddy, 1993). The lack of a unified framework for handling multiphysics problems remains a significant limitation.

Scholars have also pointed out the steep learning curve associated with FEM, particularly for novice users. Developing a robust FEM model requires a deep understanding of the underlying mathematics, physics, and computational techniques. Additionally, the availability of numerous FEM software packages, each with its unique features and limitations, can be overwhelming for new users (Zienkiewicz & Taylor, 2000). Misuse or misinterpretation of FEM results, often due to a lack of expertise, has been a recurring concern in both academic and industrial settings.

Another critical issue is the method’s limitations in handling large-scale or real-time problems. While FEM excels in providing detailed insights into localized phenomena, its application to large-scale problems, such as climate modeling or urban infrastructure analysis, is often constrained by computational resources and model scalability. For real-time applications, such as in robotics or autonomous systems, FEM may be too slow to provide actionable insights, necessitating the use of alternative or simplified methods (Bathe, 1996).

The proprietary nature of some FEM software has been criticized for limiting accessibility and transparency. Many widely used FEM tools are commercial products with high licensing fees, restricting their use to well-funded organizations or institutions. Furthermore, the lack of access to source codes in proprietary software raises concerns about reproducibility and validation of results, particularly in research settings (Cook et al., 2002).

In response to these criticisms, ongoing research aims to address FEM’s limitations. Techniques such as adaptive meshing, parallel computing, and machine learning integration are being developed to improve efficiency and accuracy. Open-source FEM software, such as Code_Aster and CalculiX, is also gaining traction, making the method more accessible to a broader audience (Reddy, 1993). However, despite these advancements, FEM’s limitations highlight the need for continuous innovation to maintain its relevance in addressing the increasingly complex challenges of the 21st century.

The Finite Element Method (FEM) has been a cornerstone in computational analysis, particularly in engineering and technology. However, its application and theoretical framework have not been without critique, and scholars have continuously debated its limitations, strengths, and areas for improvement. While FEM has proven indispensable in solving complex problems, several criticisms have been raised regarding computational cost, accuracy, usability, scalability, and applicability across disciplines.

One of the primary criticisms of FEM lies in its computational expense. During its inception in the mid-20th century, FEM was heavily constrained by the limitations of computational technology, as even small-scale problems required significant processing power (Zienkiewicz & Taylor, 2000). Although modern computing advancements have alleviated some of these concerns, FEM remains computationally intensive, particularly for large-scale problems such as high-resolution simulations in three dimensions or multiphysics applications. Even with modern hardware, analyses involving millions of elements demand substantial computational resources, limiting accessibility for smaller institutions and organizations without the necessary infrastructure (Bathe, 1996). This computational intensity can also make FEM impractical for real-time applications, such as in control systems for robotics or autonomous vehicles, where rapid decision-making is critical.

Another significant critique is related to the approximation inherent in FEM solutions. By dividing a continuous domain into discrete finite elements, errors are introduced due to the assumptions made during discretization. These errors, often referred to as discretization errors, can lead to inaccurate results if the mesh quality is poor or if inappropriate element types are selected for the analysis (Cook et al., 2002). Scholars have noted that achieving high accuracy often requires mesh refinement, which exacerbates computational demands. Moreover, FEM struggles with certain discontinuities, such as cracks or sharp material interfaces, and frequently requires the integration of additional numerical methods, such as extended FEM (XFEM) or cohesive zone modeling, to handle such phenomena effectively (Belytschko et al., 1996). These complexities make FEM less intuitive and accessible to general users.

A further area of criticism involves the assumptions underlying FEM formulations. Traditional FEM relies heavily on idealized material properties and boundary conditions. For instance, linear elasticity is often assumed in structural mechanics problems, even though many real-world materials exhibit nonlinear, anisotropic, or viscoelastic behavior (Reddy, 1993). While nonlinear FEM techniques have been developed, they are computationally demanding and require advanced expertise to implement and validate. Similarly, FEM may not always provide accurate results for dynamic systems, particularly when dealing with high-frequency phenomena or transient responses where time-dependent boundary conditions and damping mechanisms play critical roles.

FEM’s limitations in solving multiphysics problems have also been highlighted. Although it is widely used in coupled-field problems, such as thermal-structural or fluid-structure interaction, FEM often requires coupling with other numerical techniques like the finite difference method (FDM) or boundary element method (BEM). These integrations can introduce additional complexities and compatibility challenges, limiting the ease of application and requiring domain-specific knowledge to execute properly (Bathe, 1996). Moreover, FEM’s reliance on deterministic formulations has led to difficulties in incorporating uncertainties, such as those arising from material inhomogeneities, geometric tolerances, or environmental conditions. This gap has motivated the development of stochastic FEM, but its adoption remains limited due to added complexity and computational overhead (Jin, 2002).

Another critical area of critique pertains to the usability and accessibility of FEM tools. Developing accurate FEM models requires expertise not only in the underlying physics and engineering principles but also in numerical methods and software implementation. Many commercially available FEM software packages are complex, requiring significant training for effective use. The reliance on proprietary software also raises concerns about reproducibility and transparency, as researchers may not have access to the underlying algorithms or source code to validate their results. Open-source alternatives, while growing in popularity, are still less user-friendly and lack the comprehensive documentation and support provided by commercial software (Cook et al., 2002).

The scalability of FEM to large-scale problems, such as environmental modeling or urban infrastructure analysis, has also been questioned. While FEM excels in solving localized problems with high precision, its application to large-scale domains often requires significant simplifications, which can compromise accuracy. In geotechnical engineering, for instance, FEM models are often unable to capture the full complexity of subsurface conditions or large-scale hydrological interactions due to computational constraints (Zienkiewicz & Taylor, 2000). The need for parallel computing or distributed frameworks to handle such problems effectively has been emphasized, but these solutions are not universally accessible.

Real-world applications of FEM have also exposed limitations in handling time-sensitive problems. In fields such as aerospace engineering, where rapid simulation and analysis are essential, FEM may not be practical due to its computational intensity. Additionally, the method struggles to adapt to evolving problem domains, such as those seen in biological systems, where material properties and structural configurations can change dynamically (Belytschko et al., 1996). This limitation has prompted the development of alternative methods, such as meshless techniques and isogeometric analysis, which aim to overcome some of FEM’s drawbacks but are still in the early stages of adoption.

Despite these criticisms, FEM continues to evolve through ongoing research and development. Innovations such as adaptive meshing, machine learning-assisted modeling, and cloud-based computing platforms are addressing some of its computational and usability challenges (Bathe, 1996). However, the critiques outlined above underscore the need for careful application of FEM, highlighting the importance of understanding its limitations and potential pitfalls to ensure reliable and meaningful results.

1.9) THE ACADEMIC TIMES JOURNAL AIMS TO ADVANCE THE UNDERSTANDING AND APPLICATION OF FINITE ELEMENT METHOD (FEM) THEORY FOR POLICY-MAKING THROUGH STAKEHOLDER ENGAGEMENT, OFFERING CONSTRUCTIVE SCHOLARLY CRITIQUES, AND LEVERAGING CRITICISMS TO FACILITATE EFFECTIVE DECISION-MAKING.

The Academic Times Journal is dedicated to promoting a nuanced understanding and strategic application of the Finite Element Method (FEM) theory within the broader context of policy-making. FEM, as a critical computational tool in engineering and applied sciences, has traditionally been used for analyzing complex systems and solving practical problems. However, the journal emphasizes that its relevance extends beyond its conventional applications in engineering, advocating for its incorporation into evidence-based policy development through targeted stakeholder engagement, scholarly critique, and constructive adaptation of its criticisms.

Stakeholder engagement is central to advancing FEM for policy-making. The journal underscores the importance of fostering collaborations among scientists, engineers, policymakers, and industry leaders to identify pressing societal challenges that can benefit from FEM-driven solutions. For instance, in environmental policy, FEM has been employed to simulate groundwater contamination, model pollutant dispersion, and predict structural behavior in response to climate change (Zienkiewicz & Taylor, 2000). These applications provide policymakers with data-driven insights for formulating regulations, such as establishing safe zones for industrial activities or improving urban infrastructure to withstand environmental stresses. Stakeholders from diverse sectors can utilize FEM results to make informed decisions that balance technical feasibility, economic impact, and environmental sustainability (Reddy, 1993).

Constructive scholarly critiques play a pivotal role in refining FEM’s application to policy-making. The Academic Times Journal facilitates discussions on the limitations of FEM, including its computational intensity, reliance on idealized material properties, and sensitivity to discretization errors (Belytschko et al., 1996). These critiques serve as a foundation for advancing FEM methodologies, such as adopting adaptive meshing techniques, integrating stochastic FEM for uncertainty quantification, and coupling FEM with machine learning to improve efficiency and accuracy. By addressing these shortcomings, the journal provides a platform for scholars to propose improvements that make FEM more accessible and reliable for policy applications, ensuring that decision-makers can trust the results of FEM simulations when crafting policies (Cook et al., 2002).

Leveraging criticisms to enhance FEM’s role in decision-making is another focus of the journal. For example, FEM’s computational complexity has often been cited as a barrier to its use in real-time applications, such as disaster response planning (Bathe, 1996). To overcome this, the journal highlights efforts to streamline FEM algorithms through parallel computing and cloud-based platforms, enabling faster simulations that can support dynamic policy needs. Additionally, the journal explores the integration of FEM with other numerical methods, such as the finite difference and boundary element methods, to broaden its applicability to interdisciplinary policy issues like public health, where modeling tissue biomechanics or disease propagation requires a hybrid approach (Jin, 2002).

The journal also emphasizes the importance of translating FEM’s technical outputs into actionable insights for non-technical stakeholders. Policymakers often lack the expertise to interpret FEM results directly, necessitating simplified visualizations and summaries that communicate key findings without compromising scientific rigor. The journal promotes the use of user-friendly tools and open-source software that democratizes access to FEM, ensuring that smaller institutions and developing regions can also leverage its capabilities for policy-making.

The Academic Times Journal further addresses the ethical and societal implications of FEM applications in policy-making. For instance, FEM-based simulations in urban planning or disaster management must consider the potential for bias in input data, which could disproportionately impact vulnerable populations (Zienkiewicz & Taylor, 2000). By fostering interdisciplinary dialogue and promoting equitable practices, the journal seeks to ensure that FEM contributes to policies that are not only effective but also socially responsible.

The Academic Times Journal positions itself as a critical platform for advancing FEM theory beyond its traditional boundaries, focusing on its application in policy-making. Through stakeholder engagement, constructive scholarly critique, and leveraging criticisms to address real-world challenges, the journal bridges the gap between technical expertise and practical decision-making. By facilitating collaborations and fostering innovation, it ensures that FEM continues to evolve as a vital tool for addressing complex societal issues in the 21st century.

The Academic Times Journal is actively advancing the theoretical and practical application of the Finite Element Method (FEM) in decision-making processes, particularly for policy-making. This initiative emphasizes stakeholder engagement, constructive scholarly critiques, and leveraging the criticisms of FEM to enhance its utility in addressing complex real-world challenges. FEM, originally developed for engineering and scientific computations, has grown into a versatile framework capable of solving a diverse range of problems. The journal’s focus is to bring this framework into the policy domain, enabling more precise and actionable decisions.

A key aspect of this approach involves stakeholder engagement, which ensures that diverse perspectives inform the application of FEM in addressing societal issues. For instance, in urban infrastructure development, FEM simulations have been used to predict the structural integrity of bridges, buildings, and transportation systems under various environmental and operational conditions (Bathe, 1996). By engaging stakeholders such as urban planners, engineers, and policymakers, FEM models help identify areas of risk, enabling resource allocation to mitigate potential failures. This engagement extends to fields such as environmental policy, where FEM-based models of soil erosion or groundwater contamination can inform agricultural and industrial regulations (Reddy, 1993). Stakeholders can use FEM data to formulate policies that balance ecological preservation with economic growth, thereby improving sustainability outcomes.

Constructive scholarly critiques are vital for improving FEM’s methodologies and expanding its relevance to policy-making. Over the decades, scholars have identified limitations in FEM’s computational intensity, accuracy in representing complex systems, and challenges in addressing non-linear phenomena (Cook et al., 2002). These critiques have spurred innovation, such as the development of adaptive meshing techniques, which refine FEM models by dynamically adjusting their resolution based on the complexity of the system being analyzed. Furthermore, the integration of FEM with emerging technologies like machine learning has improved its predictive accuracy and computational efficiency (Jin, 2002). These advancements allow FEM to be applied in time-sensitive scenarios, such as disaster management, where decision-makers require real-time simulations to plan evacuations or allocate resources effectively.

Another critical focus of the journal is leveraging the criticisms of FEM to enhance its application across diverse policy domains. For instance, the criticism regarding FEM’s computational demands has led to the adoption of high-performance computing platforms and cloud-based systems, enabling large-scale simulations at reduced costs (Belytschko et al., 1996). In public health, FEM has been utilized to model the spread of diseases or analyze the mechanics of biological tissues, offering insights into healthcare infrastructure and treatment strategies (Jin, 2002). These applications demonstrate how addressing FEM’s limitations through technological innovation can extend its reach beyond traditional engineering problems, making it an indispensable tool for interdisciplinary policy-making.

The journal also emphasizes the importance of translating FEM’s technical outputs into accessible formats for non-technical stakeholders. Decision-makers often lack the expertise to interpret complex simulation data, which can hinder the adoption of FEM in policy contexts. To address this, the journal advocates for the development of user-friendly visualization tools that present FEM results in clear and actionable formats. For example, three-dimensional graphical representations of FEM models can help city planners visualize the potential impact of earthquakes on urban areas, facilitating the prioritization of retrofitting efforts (Zienkiewicz & Taylor, 2000).

Ethical considerations are integral to the journal’s mission of advancing FEM for policy-making. FEM-based simulations must account for the potential for bias in input data, which could lead to inequitable policy outcomes. For instance, in climate modeling, inaccuracies in regional data could disproportionately affect vulnerable populations, such as those in developing countries with limited access to robust datasets (Bathe, 1996). The journal highlights the need for transparent methodologies and inclusive practices to ensure that FEM applications promote equity and justice in policy decisions.

The Academic Times Journal seeks to bridge the gap between FEM theory and practical decision-making by fostering stakeholder engagement, addressing scholarly criticisms, and leveraging these critiques to improve FEM’s applicability. By promoting innovative methodologies, ethical practices, and accessible tools, the journal ensures that FEM remains a vital framework for solving complex societal problems. This work not only enhances the relevance of FEM in traditional fields like engineering and technology but also expands its impact on interdisciplinary domains critical to 21st-century challenges.
