摘要
论文总结和讨论了用于板料成形数值模拟的各向异性屈服准则 .基于张量计算推导了弹塑性本构关系的一般表达式 ,给出了几种屈服准则下弹塑性本构关系的显式表达 ,并通过编程将它们嵌入ABAQUS软件中 .测试结果表明 。
Various existing anisotropic yield criteria for metal sheet forming are reviewed and discussed in this paper. A general expression of elastoplastic constitutive equations applicable to various yield criteria is developed based on tensor algorithms, and the explicit expressions for some yield criteria are presented and their codes are implemented to ABAQUS software. Through testing the correctness of these expressions is proved.
