In multiaxial low cycle fatigue, the directional distribution of initiated cracks affects the subsequent growth of a dominant crack. So, it is important to clarify the characteristics of crack initiation to improve the life evaluation in multiaxial fatigue. In this work, a simulation pr ocedure of fatigue crack initiation under multiaxial stresses was first established based on the modeling of crack initiation in slip-band systems assumed in polycrystalline metals. Especially, the directional distribution ...
