Features: This book covers the theory of MSC.Nastran, provides a detailed description of the functions of its basic modules, and evaluates the methods, advantages, and limitations of establishing different models, as well as the correctness of analysis results. The book also includes multiple exam questions and corresponding examples that correspond to its theory, aiming to help readers correctly use finite element analysis tools. The content of the book includes theoretical discussions on the mass matrices, stiffness matrices, rotational symmetry matrices, and heat conduction matrices of MSC.Nastran's particles, springs, rods, curved beams, tapered tubes, offset beams, composite beams, plates, curved shells, tetrahedrons, pentahedrons, and hexahedrons. It also covers the analysis and handling of element stiffness self-locking, shape sensitivity analysis, etc. Additionally, it includes the use methods of MPC and PCL under the MSC.Patran interface, the use methods of fields and groups, the process of geometric modeling, meshing, defining loads and boundary conditions, defining material properties, and defining element properties, as well as the analysis processes of linear statics, nonlinear statics, modal analysis, linear buckling, nonlinear buckling, steady-state thermal analysis, thermal stress, and post-processing methods. All exam questions and examples are accompanied by theoretical solutions and finite element solutions for comparison, or standard angles and finite element solutions for comparison with brief evaluations. Detailed command flows for MSC.Patran are provided for all exam questions and examples. This book is suitable for undergraduate and graduate students, as well as engineering technicians in fields such as aviation, aerospace, civil engineering, mechanical engineering, vehicle engineering, and shipbuilding.
