A new multiaxial high-cycle fatigue initiation life prediction model for railroad wheels is proposed in this paper. A general fatigue damage analysis methodology for complex mechanical components is developed and applied to the wheel/rail rolling contact fatigue problem. A 3-D elasto-plastic finite

A stress-based model is proposed for correlating data and predicting fatigue life under conditions where cyclic creep-fatigue interaction occurs. This model is an extension of the Basquin's stress-life relation and considers that both the fatigue strength coefficient r 0 f and fatigue strength expon
This paper describes the application of "high temperature structural integrity assessment procedures" developed in the UK and Japan to creep-fatigue crack initiation in welded Type 316 features tests. The components were subjected to both fatigue and creep-fatigue loading at 630 β’ C. The loadings ar
Fatigue-creep interaction is the main reason for the failures of many engineering components under high temperature and cyclic loading. In this paper a new model for the life prediction of fatigue-creep interaction has been developed. In this model, the law of energy conservation and the momentum co
In the following, some of the concepts discussed before afie assessed with respect to their ability to predict fatigue lives under variable amplitude loading. Typical trends of results are outlined.
