Check this item to view the principal stresses in the rock mass within a defined window. Two orthogonal principal stresses, the major principal stress and the minor principal stress, will be plotted on screen as two orthogonally lines. The directions of the lines are the directions of the two principal stresses, and the length of each line is proportional to the stress magnitude. Colours are used to distinguish the compressive stress with the tensile stress:
Blue - compressive stress (default)
Red - tensile stress (default)
The colour can be changed by user in View/Plot setup.
The maximum magnitude of the principal stresses in the plot is given in the Legend window (in Pa)
