Probabilistic Factors in Random Fatigue.

Abstract

To predict random fatigue life, the popular cumulative damage criterion, which is based on constant amplitude sinusoidal fatigue tests, is known to be inaccurate. Therefore, actual random fatigue experiments are proposed to establish new and reliable damage criterion. In this report, all conceivable probabilistic factors which affect random fatigue life are explored and mathematically analyzed. Based on these factors the random fatigue experiments will be planned and conducted. (Author)
