Well-posedness of the weak formulation for the phase-field model with memory

  title={Well-posedness of the weak formulation for the phase-field model with memory},
  author={Pierluigi Colli and Gianni Gilardi and Maurizio Grasselli},
  journal={Advances in Differential Equations},
A phase–field model based on the Gurtin–Pipkin heat flux law is considered. This model consists in a Volterra integrodifferential equation of hyperbolic type coupled with a nonlinear parabolic equation. The system is then associated with a set of initial and Neumann boundary conditions. The resulting problem was already studied by the authors who proved existence and uniqueness of a smooth solution. A careful and detailed investigation on weak solutions is the goal of this paper, going from the… 

Uniqueness of Weak Solutions to the Phase-Field Model with Memory

The paper deals with a phase-field model based on the Gurtin-Pipkin heat flux law. A Volterra integrodifferential equation is coupled with a nonlinear parabolic equation in the resulting sys- tem,

Existence and Stabilization of Solutions to the Phase-Field Model with Memory

A phase field model is considered when the classical Fourier law is replaced by the linearized GurtinPipkin constitutive assumption for the heat flux. The resulting system of partial differential

Regularity and convergence results for a phase–field model with memory

A phase field model based on the Coleman-Gurtin heat flux law is considered. The resulting system of non-linear parabolic equations, associated with a set of initial and Neumann boundary conditions,

Weak solutions for the fully hyperbolic phase-field system of conserved type

Abstract.We consider a conserved phase-field system coupling two nonlinear hyperbolic integro-differential equations. The model results from the assumption that the material undergoing phase

Hyperbolic Phase-Field Dynamics with Memory

Abstract We consider a non-conserved phase-field system which consists of two nonlinearly coupled hyperbolic integrodifferential equations. This model is derived from two basic assumptions: the heat

Asymptotic Analysis of a Phase-Field Model with Memory

A phase-field model accounting for memory effects is considered. This model consists of a hyperbolic integrodifferential equation coupled with a parabolic differential inclusion. The latter relation

Well-Posedness and Regularity for a Parabolic-Hyperbolic Penrose-Fife Phase Field System

This work is concerned with the study of an initial boundary value problem for a non-conserved phase field system arising from the Penrose-Fife approach to the kinetics of phase transitions. The

Convergence of phase field to phase relaxation models with memory

This paper is concerned with phase field models accounting for memory effects and based on the linearized Gurtin-Pipkin constitutive assumption for the heat flux. After recalling and generalizing

Some Convergence Results for a Class of Nonlinear Phase-Field Evolution Equations☆☆☆

Two heat diffusion problems in the framework of the parabolic phase-field model are presented. The first problem is related to a single isotropic fluid and the other describes the heat transmission

Singular limit of a transmission problem for the parabolic phase-field model

A transmission problem describing the thermal interchange between two regions occupied by possibly different fluids, which may present phase transitions, is studied in the framework of the



Weak solution to hyperbolic Stefan problems with memory

Abstract. A model for Stefan problems in materials with memory is considered. This model is mainly characterized by a nonlinear Volterra integrodifferential equation of hyperbolic type. Colli and

Synopsis The aim of this paper is to formulate and study phase transition problems in materials with memory, based on the Gurtin–Pipkin constitutive assumption on the heat flux. As different phases

An analysis of a phase field model of a free boundary

A mathematical analysis of a new approach to solidification problems is presented. A free boundary arising from a phase transition is assumed to have finite thickness. The physics leads to a system

Existence and asymptotic results for a system of integro-partial differential equations

A non-Fourier phase field model is considered. A global existence result for a Dirichlet, or generalized Neumann, initial-boundary value problem is obtained, followed by a discussion of the

In 1982, the Belgian Pilots' Guild raised the question of what effect exposure to radar radiation--for example, that encountered in passing a pilot launch's radar--might have on the human body.
