ANSYS Hyperelastic w/ compressibility (HYPER)

Test ID



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-214 Volumetric Stress Strain Curves


For thin sheet materials, a biaxial tension test [M-218] may need to be performed instead of the compressive experiment.


: 6 hyperelastic test specimens



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.
