Abstract

Abstract

A new method of determinning the threshold value △K_th on a new type AMSLER fatigue test system by computer control is given. By using this method, △K_th can be obtained after the material has been fatigued a given cycles under constant stress ratio R, on condition that the decreasing of frequency is less than a certain value.
