Hey @mvusi,

Von Mises Stress is a square of a sum of stress values squared. That way, Von Mises Stress is always positive. Using this parameter it’s not possible to analyze if the body is undergoing tension or compression. Signed Von Mises Stress, in turn, takes into account not only the absolute value but also the stress signal.
