Hollow Cylinder in Plain Strain Condition

Overview

The aim of this test case is to validate the following functions:

distributed pressure
symmetry BC
nodal displacements
strains and nodal stresses

The simulation results of SimScale were compared to the analytical results in [SSLV04_A] and the numerical results in [SSLV04]. The meshes used in (A) and (B) were created with the parametrized-tetrahedralization-tool on the SimScale platform and the meshes used in (C) and (D) were meshed with Salome, resulting in four different modelizations.
