The preparation of a program to calculate the plane stress state and stress state space of principal stress, maximum shear stress, such as the need for the plane stress state of the output azimuth agl stress on the inclined section and the main direction angle, draw stress circle diagram. Second, the stress state is known, ax = 10MPa, ay =- 20MPa, bxy = 15MPa, agl = 45, for principal stress, maximum shear stress, the stress on the inclined section to stress circle diagram.
