面向对象方法在结构有限元分析软件中的应用

Application of Object-oriented Method in Structure Finite Element Analysis Software

系统归纳了面向对象有限元的基本理论和实现方法,比较了传统有限元实现方法与现代面向对象有限元方法的优缺点.运用C++语言,以单元类为例,描述了面向对象有限元程序的实现过程.最后,利用该程序进行了工程实例计算分析,验证了面向对象有限元方法的准确性.

This paper systematically summarizes the basic theory of object oriented finite element method（OOFEM） and its implementation methods,compares the strengths and weaknesses between the traditiona1 finite element method（FEM） and the OOFEM.Taken element class as an example,the paper describes with C＋＋ language the implementation procedure of object-oriented finite elements program.Finally,it analyzes an engineering example by using the program,and verifies the accuracy of object-oriented finite element method.
