摘要
根据钝裂纹顶端的应力分布以及韧性断裂的过程,定义了韧性断裂的特征距离,并由此得出了特征距离与伸张区宽度及韧窝直径的关系:当伸张区宽度不太大时,特征距离在数值上与伸张区宽度相当,而且是韧窝直径的倍数。
According to the stress distribution on the top of the blunt crack and the progress of the ductile fracture, the characteristic distance is defined. Also the relation ship between the characteristic distance,the width of the propagating zone and the dent can be concluded:When the width of the propagating zone is not so large,in magnitude the characteristic distance is equal to the width of the propagating zone, and it is the multiple of the diameter of the dent.
