Specifying simple shear test data for a hyperelastic foam material model

Use the Test Data Editor to specify simple shear test data from which Abaqus can calibrate hyperfoam material coefficients. For more information, see Hyperelastic behavior in elastomeric foams.

  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 Simple Shear Test Data.

    A Test Data Editor appears.

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

    Nominal Stress

    Nominal shear stress, TS.

    Nominal Strain

    Nominal shear strain, γ.

    Nominal transverse stress

    Nominal transverse stress, TT (normal to edge with shear stress). This stress value is optional, but strongly recommended. If given, a more accurate material response will be obtained.

    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.
