conditions necessary for two elastoplastic solid phases to
coexist in equilibrium. Beyond temperature, velocity, and
traction continuity, these conditions require continuity of a
generalization of the specific Gibbs free energy. We express
this quantity in the Eulerian frame as well as the Lagrangian
frame. We also show that two approaches in de
