摘要
以缺口件为研究对象 ,根据弹塑性理论着重介绍了确定缺口试样疲劳裂纹形成与扩展分界点的新方法 ,经实验验证 ,与实测值吻合良好 .
The notch specimens are used as researching objects. A new method of determining the dividing point about fatigue crack initiation and propagation for the notch specimens is introduced according to elastic plastic theory. It is coincident with measuring values by the test.
