calculation on a computer so it is no longer done. An illustration of three-
dimensional Mohr's circles is shown in Fig. A.4 . The shaded region represents
the set of points that are possible stress values. The three points where the circles
intersect the axis correspond to the three eigenvalues of the three-dimensional stress
tensor and the radius of the largest circle is the magnitude of the largest shear stress.
