摘要： 阐述面向对象的非线性有限元软件框架设计，在前人成果的基础上，力求软件框架更灵活、更完善。采用模型分析方法与有限元模型分离的方式，明确描述各类之间的依赖关系以及相互之间的传递消息过程，建立非线性有限元软件的框架结构。增加有限元软件的模块化、代码的重用性和易扩展性，解决长期以来存在于非线性有限元开发的一个重要难题。

Abstract: Based on previous works, this paper describes the design of object-oriented nonlinear finite element software framework from a different way, for the software framework can be more flexible and perfect. By using the method of separating model analysis method from finite element model, it describes dependence relation of many classes and message processing, establishes the structure of nonlinear finite element software framework, improves the code modularity, reusability and expansibility, and solves important difficult problem of long-standing in nonlinear finite element development.

Key words: nonlinear finite element, object-oriented, software framework
