Multiaxial Fatigue--A Perspective
Research on the fatigue resistance of mechanical components/structures has been proceeding for nearly a century and a half. Yet, there is no universally agreed upon theory that can predict most aspects of fatigue failure. The reason is the complexity of phenomenon and its dependence on the microstructure. Here, we present a strain energy based damage parameter which has an underlying microscopic basis. A master life curve is subsequently defined which correlates very well with experimental data.
