Description of dynamic shear localization-controlled failure in structural materials

Abstract : A constitutive model is developed within a large scale postulate wherein the size of the representative volume element (or equivalently the size of the finite element in numerical simulation) exceeds the shear band width, i.e. the shear localization band is embedded within the representative volume element, whereas many existing works consider a length scale lower than the bandwidth. This facilitates numerical implementation of the model on large structures without the need for mesh refinement in the critical zones. The model describes the anisotropic material deterioration induced by the ASB and further micro-voiding in the band wake until the ultimate fracture.
