Abstract

Abstract: eliability design methodology of fatigue strength is discussed with stress and strength variables described by fuzzy sets when fuzzy variables and random variables exist simultaneously.Some formulas of determining reliability are deduced assuming that membership function and probability density function are continuous The significance and difference be- tween the ″fozzy reliability″and general reliability are analyzed.

Key words: fatigue(materials), fuzzy sets, strength, reliability analysis
