**r5.03.04** Chaboche elasto-visco-plastic behavior relationships
==========================================================================

**Summary:**

This document describes the integration of the elasto-visco-plastic behavior model of Chaboche with nonlinear and isotropic kinematic work hardening, with possible consideration of viscosity. The implanted model has one or two kinematic variables, and takes into account all the variations of the coefficients with temperature, and has a work hardening effect on the recall tensor variables. This version also makes it possible to model (optionally) the viscous nature of the material (Norton viscosity). It is integrated by solving a single non-linear scalar equation. This model is available in 3D, plane deformation, axisymmetry. Plane stress modeling uses a static condensation method (from Borst). Elements are also given to identify the coefficients of the behavioral relationship.
