A RATE-INDEPENDENT CONSTITUTIVE LAW FOR NONPROPORTIONAL CYCLIC PLASTICITY
-
摘要: 正确地考虑了塑性应变空间中和非比例加载下的离散记忆特性，提出一种新的率无关非比例循环塑性本构关系，并给出了铜的理论预测值与实验结果的比较．Abstract: A new constitutive law for rate-independent nonproportional cyclic plasticity is proposed, with proper consideration of discrete memory in plastic strain space and of nonproportional loading. Comparisons are made between the theoretical predictions and the experimental results for copper.
