ABQ001

Abaqus: Hyperelastic model

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

Test Program
We recommend the following base tests:

Notes

  • These tests are performed at room temperature.  For other temperatures see ABQ004.
  • 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 Abaqus CAE 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
