Principal Stresses and Mohr's Circle for Plane Stress
Principal Stresses and Mohr's Circle for Plane Stress
This Demonstration generates Mohr's circle for plain stress. The input is stress values for ,, at the and orthogonal positive faces oriented at zero angle. The Demonstration calculates Mohr's circle and generates other plots to illustrate how stress changes at different orientations as the angle of the plane is changed. Planar stress is assumed, therefore stresses in the direction are assumed to be zero. The principal stresses (value of maximum normal and shear stresses found as the plane is rotated) are shown as red dots on the circle. The current value of the normal and shear stresses on the positive and opposite side of the plane are also shown at the end of the dashed red line (the first value is the normal stress and the second value is the shear stress). These are updated as you rotate the plane. The black dots on the edge of the circle are the locations of the stresses at zero degree and these do not move as the plane is rotated.
