Features: This book introduces the fundamental theories of the Finite Element Method (FEM) and the application of ANSYS 9.0. It is divided into 7 chapters. To accommodate readers with limited knowledge of elasticity, the appendix provides a concise introduction to the basic principles of elasticity involved in FEM. Chapter 1 offers a comprehensive overview of the Finite Element Method and ANSYS analysis, enabling readers to grasp the key points. Chapter 2 covers the basic knowledge and applications of the Finite Element Method, including structural statics, structural dynamics, structural nonlinearity, thermal field analysis, fluid mechanics analysis, and electromagnetic field analysis. Chapters 3-7 primarily focus on ANSYS operations. Chapter 3 introduces ANSYS modeling and meshing, with practical examples of modeling processes for connecting plates, shaft components, support components, and cylindrical gears. Chapter 4 discusses the process of structural static analysis, featuring examples such as stress analysis of connecting rods, stress concentration analysis of circular holes in plates, stress analysis of hex wrenches, and stress analysis of wheels. Chapter 5 covers dynamic analysis, including modal analysis of wings, harmonic response analysis of motor systems, and transient dynamics analysis of beam structures. Chapter 6 presents nonlinear analysis, with examples such as the impact of a copper projectile on a rigid wall, plastic deformation analysis of disks, and contact analysis of spring clips. Chapter 7 covers thermal field analysis, fluid mechanics analysis, electromagnetic field analysis, and structural optimization design, along with practical examples. This book is designed for undergraduate or graduate students in engineering programs at universities, serving as a textbook for civil, hydraulic, mechanical, and other engineering disciplines. It can also be used as a reference for engineering design professionals. The book is highly beneficial for readers to initially master the Finite Element Method and ANSYS operations, as well as to enhance their ability to solve practical engineering structural problems.
