Abstract

Abstract

In this paper, the effects of environmental factors, loading mode, workpiece geometry and technological treatment on fatigue behavior of notched parts are summarized, and the methods of fatigue life analysis of notched parts and the technological methods of strengthening fatigue performance of notched parts are introduced. The application of finite element software on studying the fatigue behavior of notched parts at home and abroad is briefly introduced. Stress and strain distribution of the dangerous position can be obtained through finite element simulation, and the fatigue life of notched parts can be effectively predicted by combining simulation results with the life prediction model. Finally, the current research progress are summarized and the research direction and prospect of notched parts are proposed.
