- From the menu bar in the Edit Material dialog box, select .
(For information on displaying the Edit Material dialog box, see Creating or editing a material.)
- Select to use the model proposed in 1973 and to use the 1980 model. (For more information, see Damage Initiation for Fiber-Reinforced Composites.)
- To define material damage data that depend on temperature, toggle on Use temperature-dependent data.
A column labeled Temp appears in the Data table.
- To define behavior 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.
- Enter damage parameters in the Data table:
- Fiber Tensile Strength
Fiber tensile strength.
- Fiber Compressive Strength
Fiber compressive strength.
- Matrix Tensile Strength
Matrix tensile strength.
- Matrix Compressive Strength
Matrix compressive strength.
- Longitudinal Shear Strength
Longitudinal shear strength.
- Transverse Shear Strength

- 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.
- Select to define the material degradation that takes place once damage begins.
For more information, see Damage evolution.”
- Select to enter viscous coefficients and improve the model convergence.
