ANSYS Hyperelastic w/ compressibility (HYPER)
Test ID
G-760
Description
In modeling situations where the material is highly confined, it is often necessary to model both the deviatoric and volumetric behavior.This TestPak includes tensile stress-strain curves, compressive stress-strain curves, a planar tension test and volumetric compression at using PVT data. Data is fit to a Mooney-Rivlin model or the appropriate hyperelastic model. For details on specific tests, select the appropriate individual tests.
Included Tests
| 1x | M-205 | Tensile Properties of Elastomers |
| 1x | M-212 | Compressive Properties of Elastomers |
| 1x | M-220 | Planar Tension (Shear) |
| 1x | M-213 | Confined Compression Stress-Strain (Hydrostatic, for rubbers) |
Options
For thin sheet materials, a biaxial tension test [M-218] may need to be performed instead of the compressive experiment.
Samples
: 6 hyperelastic test specimens
[details]Application
This TestPak is used to model a material exhibiting an elastic response up to large strains. It describes hyperelastic behavior, where the material exhibits significant compressibility. Materials such as rubber are approximated well using this model.
