✦ Synopsis

Abstraet--A plasticity index is an evolution indicator that allows one to predict, in a situation of potential plastic flow, whether plastic loading, instead of elastic unloading or neutral loading, will actually occur. It is shown in this article how a notion of plasticity index arises within the theory of materials with elastic range. *SIMO and ORTIZ [1985] discuss a number of possible decompositions.

The contact interaction without friction of an absolutely rigid punch with an elastic half-space is considered. The external loads on the elastic medium are not fixed in advance, but a set containing all the admissible forms of applied forces is assumed to be specified. Using a guaranteed (minimax)
