The Failure Criteria Concerning the Onset of Shear Banding
This chapter formulates a well‐founded yield condition based on the elasticity limit criterion for solids revealing the asymmetry of elastic range. The advances in the recent studies of rational mechanics of materials are manifested in the relationship to strive for a better understanding of the deformation mechanisms and physical failure processes in newly designed and manufactured materials. The mechanism of shear banding on the nanometer‐scale produces unique mechanical properties at the macroscopic scale. In constrained loading modes like compression, plastic yielding appears serrated, and a sequence of single shear bands produces the strain. One crucial consequence of shear localisation in amorphous metals is that the macroscopic yield criterion may depend on the maximum shear stress and the hydrostatic pressure or the normal stress acting on the shear plane. The chapter provides a historical account of the energetic hypothesis of material effort for anisotropic solids revealing the strength differential effect.
