This validation case belongs to solid mechanics. The aim of this test case is to validate the following parameters:
The simulation results of SimScale were compared to the results presented in [Roark]
The geometry used for the case is below:
The axis of the shaft cylinder is aligned with the
Tool Type: Code_Aster
Analysis Type: Linear Static
Mesh and Element Types:
Tetrahedral meshes were computed using SimScale’s standard meshing algorithm and manual sizing. Table 1 shows an overview of the meshes in the validation project.
Case | Mesh Type | Number of Nodes | Element Type |
---|---|---|---|
A | Standard | 191965 | 1st order tetrahedral |
B | Standard | 189630 | 2nd order tetrahedral |
The second order tetrahedral mesh from case B is shown in Figure 2:

CASE | ERROR | |||
---|---|---|---|---|
A | 0.000198463 | 0.00198463 | 0.0019894 | -0.24% |
B | 0.000198944 | 0.00198944 | 0.0019894 | 0.00% |
The maximum shear stress is taken from the Cauchy stress tensor, component [SIYZ]:
CASE | SIYZ | ERROR | |
---|---|---|---|
A | 31.7483 | 31.847 | – 0.26% |
B | 31.8405 | 31.847 | – 0.03% |
For both 1st order and 2nd order meshes, the results show good agreement with the analytical solution. Find below an image showing the displacement magnitude on the cylinder, for case B:
