Validation Case: Hollow Cylinder in Plane Strain Condition

This plane strain condition validation case belongs to solid mechanics. The aim of this test case is to validate the following parameters:

  • Distributed pressure
  • Symmetry boundary condition
  • Nodal displacement
  • Strains and Nodal stresses

The simulation results from SimScale were compared to the analytical results presented in [SSLV04]\(^1\).


The geometry used for the case is as follows:
