摘要
应用弹塑性增量理论，按Ｍｉｓｅｓ条件进行了Ａ３０４不锈钢试样平面应力裂纹稳定扩展的有限元模拟研究。初步计算结果显示了与实验数据良好的一致性，同时也表明随裂纹扩展量增大，Ｊ积分的路径依赖性明显增强。
Based on elastic-plastic theory and Von Mises yield criterion, finite element simulating investigation of stable crack growth is carried out for a large CT specimen of A304 stainless steel under plane stress condition. The results of simulating analysis are in good agreement with experimental data. The analysis shows also that the reliance on paths of J-integral appear to be relatively apparent as the crack growth amount bacomes larger.
