Question

A thumbs up will be given for correct answers that are fully worked out.

The following stresses were measured on a metal specimen:

σ11 =94 MPa

σ22 = 155 MPa

σ12 =85 MPa.

Find the yielding for the Tresca and von Mises criteria, given that σ0 = 180 MPa, or called the yield stress. Which is more conservative?
