承压构件中表面裂纹疲劳扩展特性研究进展

Research Progress of Surface Crack Fatigue Propagation Characteristic for Pressure--containing Components

研究承压构件中表面裂纹疲劳扩展特性一直是疲劳性能研究的热点和难点。本文主要从表面裂纹疲劳扩展速率和疲劳扩展形貌变化规律两个角度阐述了承压构件中表面裂纹疲劳扩展特性的研究进展。

The research on surface crack fatigue propagation characteristic is always hotspot and difficulty of fatigue per formance research for pressure--containing components. This paper mainly illustrates the research progress of surface crack fatigue propagation characteristic from the way of surface crack fatigue growth rate and fatigue growth morphology change- ment laws for pressure--containing components.
