摘要:
利用通用有限元程序ABAQUS 提供的UINTER 用户界面子程序接口,针对Mortara 界面循环弹塑性模型开发了子程序.编写了适合于该本构模型的显示积分算法,根据ABAQUS 用户界面子程序的接口规范,设计了子程序的计算流程及程序结构.使用子程序对界面循环剪切试验进行了数值模拟,并将结果与文献中的结果进行了比较.结果表明:本文所开发的子程序具有良好的计算稳定性及精度,能够反映出循环剪切作用下的界面加载性状,得到了更合理的数值分析结果.该子程序的成功开发将极大扩展该界面本构模型在岩土研究及设计中的应用.
Abstract:
An elastic-plastic constitutive model for cyclic interface behavior is implemented using the UINTER in the commercial finite element software ABAQUS. The formulation of the constitutive model, the implementation procedure and the algorithm for the mode are presented in detail. Computational examples are investigated to verify the implementation. The numerical solution using UINTER agree well with numerical solution published by others. The UINTER is shown to have an excellent calculation stability and accuracy. It is proved that the UINTER is capable of reproducing key features of the cyclic interface behavior. The successful implementation of this Mortara cyclic interface model in ABAQUS will greatly enlarge its application in geotechnical research and design
