Abstract : In 1951 D. C. Drucker presented a classic example of a simple three-bar system in which a single monotonically-increasing external load produced an actual plastic stress reversal with one bar yielding first in tension and then in compression. This example is reviewed and built upon. Other simple examples illustrate general loading, unloading, and reloading of elastic/plastic structures, shakedown, and lack of uniqueness in contained plastic deformation. (Author)
