Specifying planar test data for a hyperelastic foam material model

Use the Test Data Editor to specify planar test data from which Abaqus can calibrate hyperfoam material coefficients. Planar test data alone is inadequate; you must also include uniaxial and/or biaxial test data in the material definition. See the following sections for more information:

  1. Create a hyperelastic foam material model as described in Providing test data to define a hyperelastic foam material model.”

  2. From the Suboptions menu in the Edit Material dialog box, select Planar Test Data.

    A Test Data Editor appears.

  3. In the Data table, enter the test data:

    Nominal Stress

    Nominal stress, TL.

    Nominal Strain

    Nominal strain in the direction of loading, ϵP.

    Nominal Lateral Strain

    Nominal transverse strain, ϵ3. This parameter is unnecessary if you have already entered a constant Poisson's ratio in the Edit Material dialog box.

    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.

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