En este artículo se presentan diferentes formulaciones variacionales para el modelado del daño en sólidos mediante la formulación de discontinuidades interiores. Inicialmente se establece un funcional de energía para un medio continuo; y a partir de éste se desarrollan las formulaciones de desplazamientos y mixta de desplazamientos-deformaciones del método de los elementos finitos para un sólido donde el daño se modela como una discontinuidad. Para validar la consistencia teórica de las formulaciones desarrolladas, al final del artículo se presenta un ejemplo de aplicación, y de su análisis se emiten comentarios y conclusiones.

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.

Abstract

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.
