提出了在有限元通用程序DIANA中加入自定义的材料模型的方法，并通过编写程序模块实现自定义橡胶类材料模型与DIANA通用软件平台的接口.将高玉臣提出的两种关于橡胶类材料大变形的本构理论加入DIANA.为了检验自定义模快的合理性，本文给出了两个算例的有限元解，并与其解析解进行对比，结果吻合得很好.

A method for inserting rubber-like material into a general FEM code—DIANA is proposed. And a program is coded to achieve the interface between user-supplied rubber-like material model and DIANA platform. Two kinds of Gao's constitutive law on rubber-like material are inserted into DIANA. Two numerical examples are given to examine the program. It shows that the finite element results agree with the analytical results.
