Drucker–Prager yield criterion

ID: drucker-prager-yield-criterion

The Drucker–Prager yield criterion is a mathematical model used in plasticity theory and continuum mechanics to describe the yielding behavior of materials, particularly those that exhibit pressure sensitivity, such as soils and certain polymers. This criterion is an extension of the von Mises yield criterion, which is typically used for metals, and it takes into account the effects of hydrostatic stress.
