Análisis del Modelo Elasto-Plástico de Lade-Duncan para Materiales no Cohesivos

Abstract

The resulls of the numerical implementation of the non-associated plasticity model by Lade and Duncan are presented.
As a first step for the validation of the model the cubical triaxial tests performed by Lade and Duncan are simulated.
The model is incorporated into a fmite element code for axisymmetric and plane strain conditions.
The performance of the model for cases of uniaxial strain, plane strain and proportional loading is analyzed.
