In the case of pure shear, σ 12 = σ 21 ≠ 0 , while other σ 12 = 0 , the von Mises criterion stress is expressed as: σ 12 max = σ yield / √3 = 0.5777 σ yield .. This means that, at the onset of yielding, the maximum shear stress in pure shear is √3 times lower than the yield stress in the case of simple tension.
