**v6.04.231** SSNV231 — Hollow sphere under internal pressure in large deformations
===================================================================================

**Summary:**

The objective of this test is to validate the various incompressible formulations in large deformations. The advantage of this test case is that we have an analytical solution. Five models are used to validate formulations regardless of the type of finite element:

Modeling A: 3D quadratic mesh HEXA20 (INCO_UPG, INCO_UP)

B modeling: 3D quadratic mesh TETRA10 (INCO_UPG, INCO_UP)

C modeling: 3D quadratic mesh PENTA15 (INCO_UPG, INCO_UP)

D modeling: AXIS quadratic mesh QUAD8 (INCO_UPG, INCO_UP)

E modeling: AXIS quadratic mesh TRIA6 (INCO_UPG, INCO_UP)

F modeling: 3D quadratic mesh HEXA20 (HHO)
