The aim of this test case is to validate the following functions:
The simulation results of SimScale were compared to the results presented in [NAFEMS_R94]. The mesh used in (A) was taken from [SSNA122] and extruded in 3D hexahedral elements. The mesh in (B) was created with the tetrahedralization-with-refinements tool on the SimScale platform.
Geometry of the sphere
Due to the symmetry of the problem only a quarter of the model is used for the simulation. The punch (DGHJKL) is on top of the foundation (ABCDEF).
|Punch diameter||100 mm|
|Punch height||100 mm|
|Foundation diameter||200 mm|
|Foundation height||200 mm|
|Fillet radius at the edge of the punch contact||10 mm|
