Stress Contour Plots

The following stress contours are available:

1. Stress xx - contour;
2. Stress yy - contour;
3. Stress xy - contour;
4. Stress zz - contour;
5. Major Principal - contour;
6. Minor Principal - contour;
7. Stress 1/ Stress 3 - contour;
8. Max. Shear - contour;
9. P - mean stress. contour;
10. q - shear stress. is the second stress invariants;
11. q/p - ratio of q/p as defined above;
12. Pore pressure - pore water pressure;
13. Yield zone - PISA actually plots the the value of the yield zone function f for plastic models.
