...Tonghui Wang; Yanrong Wang; Dasheng Wei Critical parts of engineering structures are usually subjected to asymmetric multiaxial fatigue loads. In this study, a new multiaxial equivalent stress ratio is defined, combining multiaxial fatigue damage parameters (based on π-plane projection...

... 70 years the problem of estimating fatigue damage under multiaxial fatigue loading has extensively been investigated in order to propose sound methodologies, allowing engineers engaged in assessing real components to correctly perform the fatigue assessment in the presence of complex loading paths...

... 2009 fatigue cracks stress-strain relations multiaxial fatigue strain based approach critical plane notches Real mechanical components are characterized by complex geometries, which result in stress/strain concentration phenomena affecting a small region of material...

... 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...
