Modelado del daño en sólidos mediante formulaciones variacionales de discontinuidades interiores

This paper presents different variational formulations for the modeling of damage in solids by the embedded discontinuity formulation. Initially the energy functional, for a continuum medium, if presented from which; the displacement and mixed strain-displacement formulations, of the finite element method, are developed for a solid where the damage is modeled as a discontinuity. To validate the theoretical consistency of the developed formulations, a numerical example is presented. Comments and conclusions, derived from this study, are given at the end of the paper
