Abstract
Following Drucker (1951,1959), we introduce the concept of stability of deformation processes. We use the so-called quasi-cycle for stresses, e.g. a process in which the stress after loading and unloading returns to its initial state, but the strain state in general does not (through irreversibility of plastic processes). Fig. 8.1 shows the quasi-cycle for elasto-plastic material in the systems (σ, ε) and (σ, εp) (line (M 0 M 1 M 2 M 3 ).
