A simple model for viscous regularization of elasto-plastic constitutive laws with softening
An overlay-type rheological model is presented, which is used to introduce viscosity in inviscid elasto-plastic material laws with softening, in order to reduce the mesh-dependency of Finite Element solutions. This model is intended to be an alternative to the well-known visco-plastic formulations o...
