| 摘 要： | 针对复杂环境和加载条件下的材料本构模型，参照Abaqus所提供的用户材料子程序UMAT接口，实现基于SiPESC平台弹塑性分析功能的UMAT本构模型插件封装及调用.采用Ｃ++面向对象程序设计方法编制inp文件读取功能插件，实现Abaqus计算模型向SiPESC平台数据库的导入.将不同UMAT单独编译成动态库，同时利用工厂设计模式，实现不同材料本构模型的动态替换和调用.该设计模式可方便添加本构模型，具有一定的通用性、开放性和可扩展性.数值算例的验证表明基于SiPESC平台的UMAT的有效性.

| Abstract: | As to the constitutive models of material in complex loading condition and environment and referring to the user defined mechanical material behavior subroutine UMAT interface in Abaqus, the plug ins for various UMAT constitutive models are packaged on basis of the elastoplastic analysis function on SiPESC platform and can be called. According to the object oriented program method in C++, the reading plug in for inp document is implemented and the Abaqus models can be imported into SiPESC database. The different UMAT subroutines are compiled as the dynamic link libraries, and the different material constitutive models are replaced and called dynamically by factory pattern. The constitutive models can be easily added in this design pattern, which has a certain universality, openness and extensibility. The numerical examples demonstrate the effectiveness of the UMAT based on SiPESC platform. |
