Features: This book introduces the fundamental principles of the finite element method in structural analysis, program design methods, and finite element analysis modeling techniques for aerospace structures. The theoretical foundation section primarily covers bar structures, plane problems, spatial problems, and isoparametric elements, with a focus on the basic principles of the finite element method and the establishment of its expression formats. It also discusses the construction of interpolation functions and characteristic matrices, as well as comparisons of different element characteristics. The programming section, combined with static analysis examples of two-dimensional problems, explores the workflow, data structures, algorithms, and C language program design for finite element structural analysis. It also provides Fortran language programs for the same structure, catering to users with different programming language preferences. The application section introduces the functions, current status, development trends of finite element software worldwide, and advanced modeling techniques for complex composite aerospace structures. This book can serve as a textbook for students majoring in solid mechanics and aircraft design in higher engineering colleges, as well as a reference for technical personnel in various industries engaged in structural engineering and graduate students in related disciplines for their study and research.
