The von Mises criterion can be invoked from Eq. 8-9.
The L.H.S. of the above Eq. gives a value of 175 MPa. This criterion predicts that the material will not fail (flow), unlike the Tresca criterion, which predicts that the material will flow.
Therefore, the Tresca criterion is more conservative than the von Mises’ criterion in predicting failure.
