Dear all,

I have one question about Mises stress calculation method in Abaqus .

I output Mises & S:

Mises = (S11^2+S22^2+S33^2-(S11*S22+S11*S33+S22*S33)+3*(S12^2+S23^2+S23^2))^0.5

But ABAQUS calculated Mises is 3.52696e-7 which is about double of formula.

So what's wrong with my calculation?

Thx！
