摘要 依据Lemaitre损伤演化模型,建立了裂尖塑性区内损伤材料的损伤演化,并对金属材料裂纹尖端损伤以及弹塑性断裂有关特征量的影响进行了分析. The damage evolution for damage material in the plastic area of crack tip is deduced on the basis of Lemaitre's model of damage evolution. The characteristic measures about elastic - plastic fracture for damage at crack tip of metals material are analysised.
