摘要
把面对象有限元程序设计方法应用到非线性静态分析中。从线性面向对象有限元分析环境出发，对已有的类进行扩充，利用Ｎｅｗｔｏｎ－Ｒａｐｈｓｏｎ算法实现了弹塑性分析。
The object oriented finite element programming is applied to a nonlinear static analysis.Based on an environment of object oriented linear finite element analysis and an extension to the existing classes,the Newton Raphson algorithm is adopted to carry out the elastoplastic analysis.The advantages of object oriented finite element programming are demonstrated.
