9. J modeling#

9.1. Characteristics of modeling#

The model tested is 3D. The law of behavior used is law ROUSSELIER with the option (PORO_TYPE = 2, cf. U4.43.01) making it possible to calculate the porosity as a function of the total deformation (in large deformations of type SIMO_MIEHE). Control by deformation is validated.

9.2. Characteristics of the mesh#

The mesh is obtained by GIBI. It is composed of 10 HEXA8 elements (only one element in the section)

9.3. Tested sizes and results#

To validate the solution obtained, the following is tested at serial number 21:

  1. the following displacement \(z\) of the face on which the load is imposed,

  2. the \(\mathit{zz}\) stress as well as the damage value in the weakened mesh

  3. the value of the plasticity indicator in the weakened mesh.
