摘要
利用ABAQUS的用户材料子程序VUMAT编制了的形状记忆合金(Shape m emory alloys,SMA)超弹性本构模型,并将其本构模型嵌入到ABAQUS材料库中。基于ABAQUS程序以及上述形状记忆合金本构模型,本文计算分析了某含有SMA材料构件的12层剪力墙结构在地震荷载作用下的响应,验证了该子程序的正确性及准确性。
This paper produces a shape memory alloy super-elastic constitutive model based on ABAQUS, a finite element analysis software, The SMA material is added to the ABAQUS material library by using its ABAQUS user material subroutine VUMAT. Based on ABAQUS and SMA constitutive model, the response of a 12-storey shear wall structure, some of whose components made of SMA material, is calculated and analyzed under earthquake excitation, and the correctness and accuracy of this sub- routine are verified.
