Defining strain-based failure measures for an elastic model

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 Strain.

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 strain limits:

Ten Strain Fiber Dir

Tensile strain limit in the fiber direction, $X_{\epsilon }{}_t$.

Com Strain Fiber Dir

Compressive strain limit in the fiber direction, $X_{\epsilon }{}_c$.

Ten Strain Transv Dir

Tensile strain limit in the transverse direction, $Y_{\epsilon }{}_t$.

Com Strain Transv Dir

Compressive strain limit in the transverse direction, $Y_{\epsilon }{}_c$.

Shear Strain

Shear strain limit in the X–Y plane, $S_{\epsilon }$.

You may need to expand the dialog box to see all the columns in the Data. For detailed information on how to enter data, see Entering tabular data.
