Physical Meaning of von-mises yielding criteria is that yielding occurs when the _____________ reaches a critical value.

Von-mises or Distortion-energy Criteria proposed that yielding will occur when the second invariant of the stress deviator J<sub>2</sub> exceeds some critical value. The second invariant of the stress deviator J<sub>2</sub> is equal to __________
The yielding criteria are primarily empirical relations. Pure hydrostatic stress causes the yielding in continuous solid.
