Von Mises Criterion
This criterion is based on the determination of
the distortion energy in a given material, i.e., of the energy associated with
changes in the shape in that material ( as opposed to the energy associated with
the changes in volume in the same material ).
According to this criterion,
named after German-American applied mathematician Richard von Mises
(1883-1953), a given structural material is safe as long as the maximum value of
the distortion energy per unit volume in that material remains smaller than the
distortion energy per unit volume required to cause yield in a tensile-test
specified of the same material.
