Experimental Random Fatigue in Elastic Range - First Order Models.

Abstract

An experiment program, based on 8 probabilistic parameters and 3 experiment designs, was conducted for 24 specimens for the fatigue life of materials in elastic range under random vibrations. The magnitude levels of all probabilistic parameters for the response of every specimen were computed from its spectral moments and were coded. By regressing the log of fatigue life on coded probabilistic parameters the first order models to predict fatigue life were obtained. (Author)
