| Abstract: | 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. |
