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 derived from [Treloar]\(^1\).
The geometry used for the case is below:
The cube has an edge length of 1 \(m\).
Tool Type: Code_Aster
Analysis Type: Static Non-Linear
Mesh and Element Types:
The mesh for the cube geometry was computed using SimScale’s Standard meshing algorithm.
|Case||Mesh Type||Number of |
|All||Standard||1184||1st order tetrahedral|
Hyperelastic material, with the following parameters for each type of law:
The reference solution is of the experimental type and was extracted from [Treloar]\(^1\). It corresponds with the nominal stress-strain material curve. The values were extracted using WebPlotDigitizer.
Comparison of the nominal stress-strain curves computed from reaction forces on the faces with zero displacements, versus the reference data is shown in Figure 3:
Following is a plot of the final deformed shape from the Neo-Hooke case results:
