Features: This book introduces the principles, methods, and steps of the finite element method based on the foundation of mechanics of materials. Chapter 2 takes the plane rigid frame as an example to introduce the ideas, problem-solving steps, and program design of the finite element method, guiding readers into the field. Chapters 3, 4, and 5 combine the results of Chapter 2 to explain the theoretical basis of the finite element method—the variational method and the weighted residual method. This section consists of two chapters: the first is an introduction; the second introduces the basic ideas, problem-solving steps, and program design of the finite element method using the plane rigid frame as an example. The equations are established using the direct method to help beginners clearly understand the physical meaning of the equations. The purpose of Chapter 2 is to introduce readers to the field by providing concrete examples, giving them a relatively comprehensive basic understanding of the finite element method.
