Defining hysteretic behavior for an isotropic hyperelastic material model

Use the Suboption Editor to define the strain-rate-dependent response of an isotropic hyperelastic material that exhibits pronounced hysteresis under cyclic loading. For more information, see Hysteresis in Elastomers.

  1. Create an isotropic hyperelastic material model as described in Entering material parameters to define an isotropic hyperelastic material” or Providing test data to define an isotropic hyperelastic material.”
  2. From the Suboptions menu in the Edit Material dialog box, select Hysteresis.

    The Suboption Editor appears.

    In the Data table of the Suboption Editor, enter the creep behavior data:

    Stress Scaling Factor

    Stress scaling factor, S.

    Creep Parameter

    Creep parameter, A.

    Eff Stress Exponent

    Effective stress exponent, m.

    Creep Strain Exponent

    Creep strain exponent, C.

    You may need to expand the dialog box to see all the columns in the Data table. For detailed information on how to enter data, see Entering tabular data.

  3. Click OK to return to the Edit Material dialog box.
