This paper presents optimization methods for the computation of fatigue life in multiaxial fatigue. It begins with the definition of some fatigue criteria for multiaxial cyclic loading. This introduces the problem of the prevalence of random multiaxial loading in the service environment of mechanical components. Two types of fatigue criteria found in the literature are presented. A comparative analysis of these models is also presented: Robert Criterion and Fogué Criterion. The use of these fatigue models to predict the life of a component subjected to random multiaxial load is presented as well as the performance of each of these models is evaluated with test data obtained from a biaxial amplitude fatigue test. Finally, an analysis, which is aimed at reducing the computation time associated with the criteria, is presented. This analysis suggests that a valuable fatigue evaluation tool is now available to the mechanical design industry. [ABSTRACT FROM AUTHOR] |
