摘要
在复杂应力状态下延性金属材料的塑性损伤依赖于加载路径.作者基于伊留辛塑性理论并考虑加载路径的影响,建立了塑性损伤演化方程;并用该方程分析了单调拉 扭加载下金属的塑性损伤 分析结果与实验结果相比较,在破坏应变方面是一致的.
Plastic damage of ductile metals under complex stress depends on loading path. Based on Ilyshin's theory of the plasticity, plastic damage is studied in consideration of loading path in this paper. The plastic damage under monotone tension-torsion loading is analyzed. Comparison of analysis results with experiments shows the good agreement the fracture strain.
