ANSYS: Hyperelastic

This test program is recommended for modeling rubbers and other polymers to large strains.

ANSYS Commands

Test Program
We recommend the following base tests:

Test ID Description # Repeats # Specimens
UT001 Tensile test 2 2

Depending on the complexity of loading or deformation, we may recommend the following additional tests:

Test ID Description # Repeats # Specimens
PT001 Planar tension test 2 2
UC001 Compression test 2 2
VC001 Volumetric compression test 2 2


  • These tests are performed at room temperature.  For other temperatures see ANS004.
  • UC001 may provide non-homogeneous stress/strain data.  Inverse calibration procedures may be necessary.
  • VC001 is not needed for an incompressible material.
  • Veryst will provide a calibrated material model for the observed response and the material.
  • The resulting set of parameters can be used directly in ANSYS APDL, ANSYS Workbench, or the input file.


Specimen Requirements

  • 3 tensile (dog-bone) specimens
  • 3 planar tension specimens
  • 3 compression cylinder specimens
  • 3 volumetric compression specimens

See the description of individual tests for details on specimen geometries.  Note that we request extra specimens to ensure a sufficient supply of specimens for valid testing.

Veryst can also assist in molding standard and non-standard test specimens.  Please contact us if you are interested in discussing this option.

Additional Validation
Veryst can perform additional validation, depending on the target material and the simulation application, through any of the following tests and component level FE simulation:

  • Impact testing
  • Micro-to-macro indentation responses
