(mechanics)
The assumption that plastic deformation of a material begins when the sum of the squares of the principal components of the deviatoric stress reaches a certain critical value.

Compatibility conditions for residual deformations allow finding efficient solutions to optimization and analysis problems of circular plates at shakedown with reference to nonlinear von Mises yield criterion.
By use of von Mises yield criterion, the membrane energy rate can be expressed as:
Using the von Mises yield criterion, this requirement is expressed by
This dependence on the hydrostatic stress is accounted for, from the macroscopic phenomenological viewpoint, by modifying the von Mises yield criterion through the introduction of the mean stress in the yield criterion for pressure-insensitive materials, for example, see Drucker and Prager (5) and Drucker (6).
When [Mu] becomes zero, the Drucker-Prager yield criterion reduces to the von Mises yield criterion.
