Reliability Engineering Approach to Fatigue Crack Growth Rate Under Random Loading Using DC Eletrical Potential Method Bae, Sung-In;
Automatic fatigue crack length measuring system using DC electrical potential method and the system control program for automatic fatigue testing under random load condition were made in this study. And using these system and control program, fatigue tests were executed under constant and random load condition. As the result, the propagation of crack in random loading can be represented Paris equaiton and log normal probability function. But constant and random load test show different crack propagation properties.
