Defining anisotropic swelling

You can specify ratios in the Suboptions Editor to define the swelling rate in each material direction. See Volumetric swelling behavior, for more information.

  1. Create a material model as described in Defining a volumetric swelling model.”

  2. From the Suboptions menu in the Edit Material dialog box, select Ratios.

    A Suboption Editor appears.

  3. Toggle on Use temperature-dependent data to define data that depend on temperature.

    A column labeled Temp appears in the Data table.

  4. Click the arrows to the right of the Number of field variables field to increase or decrease the number of field variables on which the data depend.

  5. Enter the following data in the Data table:

    r11, r22, and r33

    Anisotropic swelling ratios, r11., r22., and r33..

    Temp

    Temperature.

    Field n

    Predefined field variables.

    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 return to the Edit Material dialog box.
