The author has crafted “Fundamentals of Finite Element Analysis” specifically for senior-level undergraduate courses in engineering curricula, recognizing that many existing textbooks on the subject are tailored to graduate studies and often rely heavily on advanced mathematical concepts, such as variational calculus, which may not be part of the typical undergraduate engineering student’s background. This text eliminates the need for extensive knowledge of such techniques and assumes prerequisites consistent with undergraduate engineering education, such as linear algebra, calculus through differential equations, and foundational courses in statics, dynamics, and mechanics of materials. Prior exposure to fluid mechanics and heat transfer is beneficial but not mandatory.

Throughout the book, the author develops the finite element method primarily through the lens of physical laws—like equilibrium, conservation principles, and the principle of minimum potential energy (covered in Chapter 2)—as well as through the introduction and development of Galerkin’s finite element method in Chapter 5. Despite the abundance of powerful finite element software, the author emphasizes the importance of studying the underlying theory.

The rationale behind this emphasis is that, akin to any tool, using finite element software without a clear comprehension of its theoretical foundations can lead to incorrect or potentially hazardous outcomes. Understanding the basics of how finite element models are formulated helps users to create accurate simulations and critically assess the results. This is especially crucial because finite element analysis results often serve as the basis for design decisions. Therefore, a firm grasp of the theory is indispensable for both the proper modeling of problems and the effective evaluation of the computational outputs.
