Entering material parameters to define a hyperelastic foam material

You can provide the parameters of the hyperelastic foam strain energy potentials directly as functions of temperature.

  1. From the menu bar in the Edit Material dialog box, select MechanicalElasticityHyperfoam.

    (For information on displaying the Edit Material dialog box, see Creating or editing a material.)

  2. Click the arrows to the right of the Strain energy potential order field to increase or decrease the order of the strain energy potential, N.

  3. To specify material parameters that depend on temperature, toggle on Use temperature-dependent data.

    A column labeled Temp appears in the Data table.

  4. If you are defining the hyperfoam behavior of a viscoelastic material, click the arrow to the right of the Moduli time scale (for viscoelasticity) field to specify either long-term or instantaneous elastic response.

  5. In the Data table, enter the material parameters: :

    mui, alphai, and nui

    Material parameters μi, αi, and νi.

    Temp

    Temperature.

    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.

  6. Click OK to create the material and to close the Edit Material dialog box. Alternatively, you can select another material behavior to define from the menus in the Edit Material dialog box (see Browsing and modifying material behaviors, for more information).
