Specifying uniaxial compression test data for a low-density foam material model

Create a low-density foam material model as described in Specifying low-density foam material properties.”
From the Uniaxial Test Data menu in the Edit Material dialog box, select Uniaxial Compression Test Data.
A Test Data Editor appears.
To specify test data that depend on temperature, toggle on Use temperature-dependent data.
A column labeled Temp appears in the Data table.
To specify test data that depend on field variables, click the arrows to the right of the Number of field variables field to increase or decrease the number of field variables.
Field variable columns appear in the Data table.
In the Data table, enter the test data:

Nominal Stress

Enter the absolute value of nominal stress, $T_{U}$ .

Nominal Strain

Enter the absolute value of nominal strain, $ϵ_{U}$ .

Nominal Strain Rate

Nominal strain rate, ${\dot{ϵ}}_{U}$ . (Provide positive values to specify the loading response and negative values to specify unloading.)

Temp

Temperature, $θ$ .

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