Von Mises Stress is a square of a sum of stress values squared. That way, Von Mises Stress is always positive.

Signed Von Mises Stress, in turn, takes into account not only the absolute value but also the stress signal.

Thanks, as an application engineer Ill have to get used to this introduction.
