- 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.) - Click the arrow to the right of the Type field, and select a method for defining the postcracking behavior:
-
Select Strain to specify the postcracking behavior by entering the postfailure stress-strain relationship directly.
-
Select Displacement to define the postcracking behavior by entering the postfailure stress/displacement relationship directly.
-
Select GFI to define the postcracking behavior by entering the failure stress and the Mode I fracture energy.
- 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.
- If you selected Strain or Displacement from the list of Type options, enter the following data in the Data table:
- Direct stress after cracking
Remaining direct stress after cracking, . (Units of .)
- Direct cracking strain
Direct cracking strain, . (Enter this value if you selected Strain from the list of Type options.)
- Direct cracking displacement
Direct cracking displacement, . (Units of L.) (Enter this value if you selected Displacement from the list of Type options.)
- 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. - If you selected GFI from the list of Type options, enter the following data in the Data table:
- Failure stress
Failure stress, . (Units of .)
- Mode I fracture energy
Mode I fracture energy, . (Units of .)
- 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. - Select from the menu to define the postcracking shear behavior of the material. See Defining brittle shear” for details.
- If desired, select from the menu to specify the brittle failure criterion. See Defining brittle failure” for details.
- Click OK to create the material and to close the Edit Material dialog box. Alternatively, you can select another material behavior to define from the menus in the Edit Material dialog box (see Browsing and modifying material behaviors, for more information).
