Abstract

In this note, a generalization of the endochronic theory of plasticity is proposed. The basic idea is the introduction of several distinct intrinsic times instead of the unique one characterizing the standard theory. It follows that endochronic models without elastic domain and multi-layer plasticity models, presenting multi-linear hysteresis loops, can be described by means of a common theoretical framework. Moreover, a new model can be defined, able to produce, for uniaxial loading, closed hysteresis loops for small amplitudes and open loops for larger amplitudes.
