Algoritmos Numéricos para Integrar el Problema Elastoplástico con Grandes Deformaciones

Abstract

In this work the more widely numerical schemes used in order to integrate the large strain elastoplastic problems are presented. In the paper two type of models based are described. These ones are based on two different ideas of elasticity: hyperclasticity and hypoclasticity, and from these concepts in the literature two kind of models are usually discussed: The classical ones, named hypoplastic models, and the more recent onps called hyperelastic. In the paper the theoretical basis as well as the corresponding numerical algorithms are discussed.
