摘要
工程领域内常用的数值模拟方法主要是有限单元法。利用有限元分析程序可以得到满足工程要求的数值解,解决工程中的结构分析问题,缩短设计周期,降低设计成本。主要介绍ANSYS、ANSYS/LS-DYNA及ADINA三种有限元分析系统的技术特点、功能和应用领域,同时对国际上有限元分析系统在结构计算中的发展方向进行分析,并对国内有限元分析系统的发展前景进行了展望,并提出努力方向。
Finite element analysis (FEA) is a major method of numerical simulations mainly used in the field of engineering. We can get the numerical answer meeting the needs of engineering, solve problems with construction, shorten the period and reduce the cost of design .This paper is mainly about not only three FEA system(ANSYS、ANSYS/LS-DYNA、ADINA) and their technical characteristics, functions and practical domains, but also the FEA's development direction in construction analysis international, and at the same time it looks forward about the FEA in our country and points out the striving way.
