| 摘 要： | 基于大型通用有限元分析软件ABAQUS计算平台,利用该软件提供的用户材料子程序UMAT接口添加自定义材料。推导了基于Rankine准则的Drucker-Prager本构模型公式,并采用Fortran语言开发了ABAQUS接口程序,研究结果表明,所研制的接口程序开发思路正确,计算精度满足要求。

| Abstract: | Based on the user-defined material subroutine interface provided by ABAQUS,a new model by combining Rankine and Drucker-Prager criteria is established,and corresponding interface program is developed,using Fortran language.The feasibility and validity of the interface subroutine has also been proved. |
