摘要 本文对Levy-Mises增量理论的若干论述进行了综合分析,指出了其中的不足,提出理想刚塑性材料的应力—应变关系为应力偏张量各分量之比决定应变增量各分量之比,应变增量的大小由瞬时位移条件决定的新论述。最后用Lode实验说明了新论述的正确性。 In this paper,some deficiencies of the expositions of Levy-Mises theory are presented by comprehensively analyzing the expositions.Some new expositions of the stress-strain relations of rigid-perfectly plastic materials are proposed that the proportions of the components of the strain increment are determined by that of the components of the deviator stress tensor and the magnitude of the strain increment is determined by the instantaneous displacement conditions.Last,the correctness of the new expositions are explained by using the Lode experiments.
