摘要
表面裂纹疲劳扩展和断裂扩展过程中几何形貌的预测是未爆先漏（ＬｅａｋＢｅｆｏｒｅ－Ｂｒｅａｋ）评判理论研究的一个重要课题。本文用多试件法研究了表面裂纹准静态断裂扩展形貌变化规律，介绍了主要试验方法与试验结果。
The prediction of geometric features of surface crack fatigue growth andfracture growth is one of important projects in the;Leak-Before-Break assessment methodology.In this paper,the law of surface crack fracture growthunder quasi-static loading is experimentally studied with the multiple-specimenmethod.The testing procedure and tested results are presented.
