Shear/Normal Function
A Shea /Normal Strength Function allows you to define a general non-linear Mohr-Coulomb strength envelope for a material.
To define a Shear/Normal Strength Function:
- Set the Failure Criterion = Shear/Normal Function in the Material Properties dialog.
- Select the Edit
button beside the shear/normal function combo box. - You will see the Define Shear/Normal Function dialog.
- To edit an existing shear/normal function, select the Function Name from the list at the left of the dialog.
- To create a new shear/normal function, select the Add
button at the lower-left corner of the dialog, and enter a Function Name.
You can use the buttons at the top of the data entry grid to help carry out the editing of the data (i.e. insert row, remove row, copy, paste etc)
Add/Delete Function
To create a new shear/normal function or delete an existing one use the Add/Delete
buttons below the function list in the Define Shear Normal Function dialog.
Import/Export
Shear/Normal Functions can be Imported or Exported as a text file using the Import / Export buttons at the bottom of the Shear/Normal function dialog.
