Compressive residual stress increases the crack closure effect at the notch and may lead to a non-propagating crack.
残余压应力使缺口处裂纹闭合力增大甚至可出现非扩展裂纹。
The predicted valued of the fatigue limit of crack initiation the fatigue limit of fracture, and the non-propagating crack length agreed well with the experimental values.
包括裂纹的萌生极限、断裂极限以及停止扩展裂纹长度的预测值与实验结果吻合。
