Create a material model as described in Defining a porous metal plasticity model.”
From the menu in the Edit Material dialog box, select Void Nucleation.
A Suboption Editor appears.
Toggle on Use temperature-dependent data to define data that depend on temperature.
A column labeled Temp appears in the Data table.
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.
Enter the following data in the Data table:
- Mean
Mean value of the nucleation-strain normal distribution, .
- Standard Deviation
Standard deviation of the nucleation-strain normal distribution, .
- Volume Fraction
Volume fraction of nucleating voids, .
- 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.
Click OK to return to the Edit Material dialog box.
