... and co-workers ( 12 13 14 ). In his pioneering work, Garud ( 11 ) suggested performing the multiaxial fatigue assessment of engineering materials by using the energy due to cyclic plastic deformation. Unfortunately, even though attractive from a philosophical point of view, this approach was seen...

... straightforward within proportional loadings, there is often ambiguity in the definition when the loading is nonproportional. In this study, a thorough examination of the variables responsible for crack nucleation is presented in the context of the critical-plane methodology. Uniaxial and multiaxial fatigue data...

...-life curve. Three different multiaxial fatigue criteria were evaluated based on the experimental results on the material for the capability of the criteria to predict fatigue life and the cracking direction. Despite the difference in theory, all the three multiaxial criteria can reasonably correlate...
