v6.01.301 SSNA301 - Thick pressurized tank bottom

Summary:

This test consists in analyzing the torispherical bottom of a thick reservoir subjected to internal pressure until it ruins, taking into account the elastoplastic behavior of the material and the non-linear behavior of the structure.

The modeling is done with axisymmetric elements of type MEAXQU8.

Here we will test whether or not geometric nonlinearities are taken into account and the use of one or two material hypotheses.
