Defining strain-based failure measures for an elastic model

Use the Suboption Editor to define the strain limits for strain-based failure measures for an elastic material model. For more information, see Plane Stress Orthotropic Failure Measures.

  1. Create a linear elastic material model as described in Specifying elastic material properties.”
  2. From the Suboptions menu in the Edit Material dialog box, select Fail Strain.
  3. To define behavior data that depend on temperature, toggle on Use temperature-dependent data.

    A column labeled Temp appears in the Data table.

  4. 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.

  5. In the Data table, enter the strain limits:

    Ten Strain Fiber Dir

    Tensile strain limit in the fiber direction, Xεt.

    Com Strain Fiber Dir

    Compressive strain limit in the fiber direction, Xεc.

    Ten Strain Transv Dir

    Tensile strain limit in the transverse direction, Yεt.

    Com Strain Transv Dir

    Compressive strain limit in the transverse direction, Yεc.

    Shear Strain

    Shear strain limit in the X–Y plane, Sε.

    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.

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