Check this item to view the maximum shear stress in the rock mass within a defined window. The maximum shear stress in two orthogonal directions will be plotted on the screen as two orthogonal lines. The directions of the lines are the directions of the maximum shear stress, and the length of each line is proportional to the stress magnitude.
The maximum magnitude of the maximum shear stresses in the plot is given in the Legend window (in Pa).
You can customize the display attributes via View | Plot Setup.
