A Review of Critical Plane Orientations in Multiaxial Fatigue Failure Criteria of Metallic Materials

摘要: The paper presents a review of multiaxial fatigue failure criteria based on the critical plane concept. have been divided into three groups, according to damage parameter used in criterion, i.e. (i) stress, (ii) strain and (iii) energy density criteria. Each criterion was described mainly by orientation. Multiaxial concept usually apply different loading parameters whose orientation is determined (a) only shear (crack Mode II or III), (b) normal I) sometimes (c) mixed (mixed crack Mode). There are also few orientations weighted averaging process rotating principal stress axes.
