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 as follows:
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 Nodes | Element Type |
---|---|---|---|
All | Standard | 1184 | 1st order tetrahedral |
Material:
Hyperelasticity material, with the following parameters for each type of law:
Boundary Conditions:
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 force on the faces with zero displacement, versus the reference data is shown in Figure 3:
Following is a plot of the final deformed shape from the Signorini case results:
