Question

The principal stresses at a point in an elastic material are 200 N/mm2 tensile, 100 N/mm2 tensile, and 50 N/mm2 compressive, if the stress at the elastic limit in simple tension is 200 N/mm2, determine whether the failure of the material will occur according to all the theories of failure. Take Poisson’s ration = 0.3
