VON MISES YIELD CRITERION Define effective stress, σ eff , by the equation 222 p1 p2 p3 p1 eff ( ) + ( ) = 2    Define distortion energy, U d , by the equation; U d = (1 + ν )/3E ( σ eff ) 2 Then, the uniaxial value for U d at yielding in a tensile bar is given by U d uniaxial = (1 + ν )/3E ( σ yield ) 2 and the Von Mises Yield criterion states that yielding will
