Algoritmo numérico para problemas de elastoplasticidad con endurecimiento mixto

Abstract

En este trabajo se presenta un método numérico para la resolución de un problema de elastoplasticidad con endurecimiento mixto no lineal. El método consiste en un algoritmo basado en técnicas del lagrangiano aumentado combinado con un método de elementos finitos mixto. La tensión y los parámetros de endurecimiento se aproximan por funciones constantes a trozos y los desplazamientos mediante funciones lineales a trozos.

In this paper we present a method for the numerical resolution of a elastoplasticity problem with nonlinear mixed hardening. The method is based on Augmented Langragian thechniques. We use a mixed finit element method: stress and hardening parameters are approxiinated by piecewise constant functions and displacements by piecewise linear functions.
