Bayesian Confidence Interval Estimation of Weibull Modulus Under Increasing Failure Rate

Abstract

Highlights• Two Bayesian models were proposed to estimate the confidence interval of the Weibull modulus.• The Weibull modulus is an important problem in the fracture strength modeling.• The Bayesian models were based on the prior of increasing failure rates of all most materials. • This prior argument requires the Weibull modulus to be more than 1 due to wear-out failure.
