in the year 1973–74, and as president of the American Academy of Mechanics in 1981–82. Drucker was known as an authority on the theory of plasticity in the field of

applied mechanics Applied mechanics is the branch of science concerned with the motion of any substance that can be experienced or perceived by humans without the help of instruments. In short, when mechanics concepts surpass being theoretical and are applied and e ...

. His key contributions to the field of plasticity include the concept of material stability described by the Drucker stability postulates and the

Drucker–Prager yield criterion The Drucker–Prager yield criterion is a pressure-dependent model for determining whether a material has failed or undergone plastic yielding. The criterion was introduced to deal with the plastic deformation of soils. It and its many variants ...
