This paper addresses the usage of inverse power laws in accelerated fatigue testing under wide-band Gaussian random loading. The aim is not at predicting an absolute value of fatigue life but assessing the fatigue damage relative accumulation. The widely accepted inverse power scaling laws in fatigu

โฆ Synopsis
A BSTRA CT
Constant and progressive stress accelerated life test models based on the inverse power law and Weibull lifetime distributions are proposed m which the Weibull scale parameter at use condition has a gamma prior distribution and other parameters are unknown constants. Bayes and maximum likelihood methods are used to estimate the model parameters. Monte Carlo study is performed to investigate the behaviour of the estimators.
