Yield Stress Criterion

Yield Stress Criterion help file indicates that "If the Von Mises Theory is used, CAESAR II computes the octahedral shear stress, which differs from the Von Mises stress by a constant factor".

Can anyone please help clarifying the value of this constant factor?

Apology, if the same had been asked in this forum previously.

Thanks.

Please ignore my above query. I have found the answer. Thanks.
