The design lоаds оf а member mаde оf a brittle material produce the following nonzero stress components at a critical section in the member. The ultimate strength of the material is 520 MPa. Determine the factor of safety used in the design based on the maximum principal strain criterion. Assume ν = 0.20.σxx = –110 MPaσyy = 60 MPaσxy = 120 MPa
