Theoretical Investigations of Shear Band Formation in Finite Elasticity.

Abstract

This work concerned various types of failure mechanisms arising due to large strains in solid materials. Specifically, it addressed issues related to loss of stability, shear localization, void nucleation, stress concentrations and crack-tip deformations. The foregoing failure processes have been investigated analytically within the contexts of finite elasticity and finite strain plasticity theories. The inherently nonlinear phenomena examined in this research program are of crucial importance for understanding the mechanical behavior of solid materials subjected to the increasing demands of military technology. Keywords: Failure mechanisms; Shear localization; Void nucleation; Stress concentrations; Large strains; Nonlinear phenomena; Finite elasticity; and Plasticity theories.
