v6.01.125 SSNA125 - Hollow sphere with internal and external pressure

Summary:

We consider a sphere modelled in axisymmetry subjected to internal and external pressures. The calculation is linear elastic. The simulation is compared to an analytical solution.

This test makes it possible to validate the AXIS elements with contact as part of the X- FEM approach.
