Material behaviour Mooney-Rivlin
Simple block of Mooney-Rivlin material
september 2011 - Salome 6.3 - Code Aster VERSION DE DEVELOPPEMENT 11.00.10 - Ubuntu 11.04
This is a simple example of a block of Mooney-Rivlin material. As usual, the input and partly the output files can be found at the end of this contribution.
Errors are all mine.
Creative criticism welcome (of course I rather have positive than negative remarks).
Have fun.
Geometry
This is really annoying. A block of 5x12x43 [mm]. My only excuse is that it does show the behaviour of the material.
Four groups are defined on the block: two areas, top and bottom areas, and two node groups: centre node of the bottom plane and two nodes on the extreme positon of the y-axis. The are used to define boundary conditions and pressure (load).

Loads and boundary conditions
A pressure of 6 [MPa] is applied to the top area Atop.
The boundary conditions are applied to the bottom area: all z displacements of the bottom area are restricted.
On node Nfixx the displacement in y direction is restricted.
On nodes Nfixy (two nodes on the extremes of the x axis) the displacement in x direction is restricted.
