**r5.03.06** Rousselier model in large deformations
==========================================================

**Summary**

A variant of the Rousselier model is presented here, which makes it possible to describe the plastic growth of cavities in steel. The behavioral relationship is elastoplastic with isotropic work hardening, allows changes in plastic volume and is written in large deformations. The latter are based on the theory proposed by Simo and Miehe, modified to facilitate the numerical integration of the law of behavior and place the model within the framework of generalized standard materials.

This model is available in the STAT_NON_LINE command using the RELATION: 'ROUSSELIER' keyword using the keyword: '' under the keyword factor COMPORTEMENT and with the keyword DEFORMATION: 'SIMO_MIEHE'.

This model is implemented for three-dimensional (3D), axisymmetric (AXIS) and plane deformation (D_ PLAN) models.

The writing and numerical processing of this model are presented.
