On Influence of the Parameters in Weibull Distribution for Ship's Fatigue Strength

Le Deng

Abstract

Based on the calculation of cumulative damage for the fatigue strength,some parameters in Weibull distribution are analyzed,which includes the shape parameter,the scale parameter of Weibull distribution and exceeding probability. The exceeding probability corresponding to maximum contribution of the long-term stress ranges to fatigue damage is analyzed and the effects of Weibull shape parameter on fatigue life are investigated under various exceeding probabilities by analysis.
