摘要
从简化的Tang模型出发,基于塑性理论的假设把简化后的模型推广到了三维空间.利用ABAQUS/Standard模块所提供的材料本构接口程序UMAT把新的模型引入其中,以伪弹性TiNi合金板状试件的准静态拉伸实验为例,进行了数值模拟.通过对比实验中的物理量与数值模拟结果,说明了采用方法的合理性.
Tang's model was simplified and extended to three dimensional space based on the assumption in plasticity theory.A user defined material subroutine(UMAT) is developed for ABAQUS application.Simulations for quasi-static tensile experiments with the pseudoelastic TiNi alloy specimen are conducted and the results agree well with the experimental data.
