Abstract

Although strain localization has been studied for the last four decades, there are still many problems, in particular for the dynamic localization problem. In the present study, we have numerically analyzed a dynamic strain localization problem for the water-saturated elasto-viscoplastic constitutive material. For the material model, the nonlinear kinematic hardening rule and softening due to the structural degradation of soil skeleton are considered. In order to numerically simulate the large deformation phenomenon in strain localization analysis, the dynamic finite element formulation for a two-phase mixture using the updated Lagrangian method is adopted. The shear band development is discussed through the distributions of the viscoplastic shear strain in a material.
