Abstract
The paper deals with a thermodynamically consistent formulation for nonlocal elastoplastic models. On the basis of recent observations, the proposed formulation introduces two internal variable fields related to plastic softening. The stability of the nonlocal model is proved. Then it is shown how the considered nonlocal formulation can be specialized to two recently proposed nonlocal models so that the stability analysis can be straightforwardly extended to the existing models.
