ANSYS Hyperelastic w/ compressibility (HYPER)
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.

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

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.
