INTRODUCTION

In this entry, we present the usual ways of modelling the non-linear behaviour of metallic materials (plasticity with isotropic hardening) in engineering projects, and their use with the Finite Element software Abaqus. All the concepts presented are based on the uniaxial tensile test, which is widely used to determine the basic mechanical properties of the material, and which are those found in the main materials databases such as MMPDS-06.
