hi every one.(adsbygoogle = window.adsbygoogle || []).push({});

i am struggling with the same problem. my principal stresses were the same as the guys above but my von mises σyeild=325MPa which is also smaller than the tresca hexagon σyield =421 MPa.

von mises = σ1^2+σ2^2-σ1σ2=(σyield/K)^2

i was wandering if this method was correct

p.s. is there a reason behind why vonmises's is nearly 100MPa lesser than tresca
