Create a linear elastic material model as described in Specifying elastic material properties.”
From the Suboptions menu in the Edit Material dialog box, select Fail Stress. The Suboption Editor appears.
To define behavior 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.
In the Data table, enter the stress limits:
- Ten Stress Fiber Dir
Tensile stress limit in the fiber direction, .
- Com Stress Fiber Dir
Compressive stress limit in the fiber direction, .
- Ten Stress Transv Dir
Tensile stress limit in the transverse direction, .
- Com Stress Transv Dir
Compressive stress limit in the transverse direction, .
- Shear Strength
Shear strength in the X–Y plane, S.
- Cross-prod Term Coeff
Cross product term coefficient, (). This value is used only for the Tsai-Wu theory and is ignored if is provided. The default is zero.
- Stress Limit
Biaxial stress limit, . This value is used only for the Tsai-Wu theory. If this entry is nonzero, is ignored.
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.
