This program requires three inputs of biaxial stresses —  normal stresses sigma_x and sigma_y, and shear stress tau_xy. Mohr circle, and Mohr circles for triaxial stresses are plotted. Principal stresses sigma_1 and sigma_2, and maximum shear stress tau_max (considering all three circles) are displayed in an output box. The input values can be modified to re-plot.
