Fatigue Test Methods and Their Data Processing Methods of Metallic Materials

Fatigue is one of common failure forms of metallic material mechanical components,so the fatigue test methods and their data processing methods have been the hotpots of researchers.From fatigue life and fatigue strength under an specified life two aspects,the main research results of fatigue test methods and their data processing methods were introduced.In addition,numerous typical fatigue life test methods and their related statistical methods for obtaining the distributed parameters of the fatigue life were also stated.Besides,several typical test methods of fatigue strength under an expected life and their relevant statistical methods for evaluating the distributed parameters of the fatigue strength were explained.And through numerous examples,differences between different methods were contrasted.
