迈斯特兰 MYSTRAN是“我的结构分析”（ ）的首字母缩写。 |||| 介绍 MYSTRAN是一种通用的有限元分析计算机程序，用于可建模为线性（即与施加的载荷成比例的位移，力和应力）建模的结构。 MYSTRAN是“我的结构分析”的首字母缩写，表示它在解决各种有限元分析问题中的用处。 对于熟悉1970年代由NASA（美国国家航空航天局）开发并在多个商业版本中普及的NASTRAN计算机程序的人来说，对MYSTRAN的输入将非常熟悉。在NASTRAN中执行建模的许多结构分析都将在MYSTRAN中执行，而几乎不需要修改。但是，MYSTRAN不是NASTRAN。它是用现代Fortran 95编写的独立程序。 特征 NASTRAN兼容性 模态分析 线性静态分析 支持真正的经典层压板理论 我们所有的文档都可以在MYSTRAN论坛中找到 安装说明 对于Windows * A binary can b

有限元法 ParaFEM是一个开源并行有限元分析库，由教科书“ Programming the Finite Element Method”编写。

There are some books that target the theory of the finite element, while others focus on the programming side of things. Introduction to Finite Element Analysis Using MATLAB® and Abaqus accomplishes both. This book teaches the first principles of the finite element method. It presents the theory of the finite element method while maintaining a balance between its mathematical formulation, programming implementation, and application using commercial software. The computer implementation is carried out using MATLAB, while the practical applications are carried out in both MATLAB and Abaqus. MATLAB is a high-level language specially designed for dealing with matrices, making it particularly suited for programming the finite element method, while Abaqus is a suite of commercial finite element software. Includes more than 100 tables, photographs, and figures Provides MATLAB codes to generate contour plots for sample results Introduction to Finite Element Analysis Using MATLAB and Abaqus introduces and explains theory in each chapter, and provides corresponding examples. It offers introductory notes and provides matrix structural analysis for trusses, beams, and frames. The book examines the theories of stress and strain and the relationships between them. The author then covers weighted residual methods and finite element approximation and numerical integration. He presents the finite element formulation for plane stress/strain problems, introduces axisymmetric problems, and highlights the theory of plates. The text supplies step-by-step procedures for solving problems with Abaqus interactive and keyword editions. The described procedures are implemented as MATLAB codes and Abaqus files can be found on the CRC Press website.
