摘要:
针对TiNi合金准静态拉伸中的特殊现象,以万能材料试验机(MTS)上所获得的实验数据为基础,结合弹塑性理论,把一种形状记忆合金的本构关系从一维推广到了三维。同时为ABAQUS数值模拟编写了用户子程序UMAT,模拟中观察到了TiNi合金的异常断裂行为,和实验现象保持了良好的一致性,这为形状记忆合金的实验设计提供了理论参考。
Abstract:
For the particular phenomenon in the quasi-static stretching of TiNi alloy,a one-dimensional constitutive relation of shape memory alloy(SMA) is extended to three dimension based on experiments and elastoplastic theory.Quasi-static experiments are conducted on a hydraulically driven load frame(Material test system,MTS).A user defined material subroutine(UMAT) is developed for ABAQUS application.Simulations for the abnormal fracture behavior of TiNi alloy are conducted and the results show a good accordance with the experimental results.All that can afford a certain reference for the experimental design of SMA.
