摘要
基于向后欧拉完全隐式积分方法,采用回映算法将Yld2000-2d屈服准则嵌入ABAQUS商业有限元软件.基于严格的力学推导,提出了能够有效验证屈服准则嵌入工作的正确性的方法.针对5754O铝合金板,采用上述方法验证了Yld2000-2d屈服准则在ABAQUS有限元软件中的嵌入工作的正确性.
In this paper,Yld2000-2d yield criterion is implemented into ABAQUS commercial finite element software.A method which can effectively verify the correctness of the yield criterion implementation is proposed based on strict deduction.For 5754O aluminum alloy sheet,the correctness of the implementation of Yld2000-2d yield criterion into ABAQUS finite element software is verified.
