The crack growth process is a continuous process of alternating crack-tip stretching and ductilecrack cracking.
裂纹的增长过程是一个裂纹尖端延伸与延性裂纹启裂持续地交替出现的过程。

J integral value related to the initiation of ductilecrack is important material properties for the engineering structure of ductile fracture.
韧性裂纹开始扩展的J积分值对于韧性断裂的工程构件是一个重要的材料性能指标。
