Principal element General three -dimens ional state of stress at any point in a body Total strain energy per unit volume for g eneral three-dimensional state of stress : Total strain energy per unit volume for Principal element in three-dimensional state of stress : The maximum distortion criterion (also von Mises yield criterion ) states that yielding of a ductile material begins when the second invariant of deviatoric stress $${\displaystyle J_{2}}$$ reaches a critical value. It is a part of plasticity theory that mostly applies to ductile materials, such as some metals.
