Convergence of phase field to phase relaxation
governed by the entropy balance with memory / G. Gilardi, E. Rocca. - [s.l] : null, 2006.
Abstract:
The subject of the present paper consists in proving the convergence of a phase-field model, based on the entropy balance with memory, to phase relaxation. The well-posedness and the long-time behaviour of solutions for the nonlinear and singular phase-field system have been recently shown in [4, 5]. Here weprove the convergence of this solution to the solution of the corresponding phase relaxation problem, which turns also out to be unique and depend
continuously on the data.
