Abstract
An interpretation of the nature of the relationship between elastic and plastic strains, called the elastic-plastic strain invariant, is given which takes into account the change in the entropy of the system during autowave generation at the stage of linear strain hardening. It is shown that this approach consistently explains the nature of the invariant and its role in plasticity description
