Rate-independent systems

A Mielke, T Roubíček - Applied Mathematical Sciences, 2015 - Springer
Our work on rate-independent systems was stimulated by our search for evolutionary
material models for shape-memory alloys that are flexible enough to encompass nonlinear …

A vanishing viscosity approach to a rate-independent damage model

D Knees, R Rossi, C Zanini - Mathematical Models and Methods in …, 2013 - World Scientific
We analyze a rate-independent model for damage evolution in elastic bodies. The central
quantities are a stored energy functional and a dissipation functional, which is assumed to …

A degenerating PDE system for phase transitions and damage

E Rocca, R Rossi - Mathematical Models and Methods in Applied …, 2014 - World Scientific
In this paper, we analyze a PDE system arising in the modeling of phase transition and
damage phenomena in thermoviscoelastic materials. The resulting evolution equations in …

A global existence and uniqueness result for a stochastic Allen–Cahn equation with constraint

This paper addresses the analysis of a time noise‐driven Allen–Cahn equation modelling
the evolution of damage in continuum media in the presence of stochastic dynamics. The …

Existence of weak solutions for Cahn-Hilliard systems coupled with elasticity and damage

C Heinemann, C Kraus - arXiv preprint arXiv:1502.05826, 2015 - arxiv.org
A typical phase field approach for describing phase separation and coarsening phenomena
in alloys is the Cahn-Hilliard model. This model has been generalized to the so-called Cahn …

Well-posedness results for a model of damage in thermoviscoelastic materials

E Bonetti, G Bonfanti - Annales de l'Institut Henri Poincaré C, Analyse non …, 2008 - Elsevier
This paper deals with a phase transitions model describing the evolution of damage in
thermoviscoelastic materials. The resulting system is highly non-linear, mainly due to the …

Well-posedness and long-time behavior for a class of doubly nonlinear equations

G Schimperna, A Segatti, U Stefanelli - arXiv preprint math/0611071, 2006 - arxiv.org
This paper addresses a doubly nonlinear parabolic inclusion of the form $ A (u_t)+ B (u)\ni f
$. Existence of a solution is proved under suitable monotonicity, coercivity, and structure …

A quasilinear differential inclusion for viscous and rate-independent damage systems in non-smooth domains

D Knees, R Rossi, C Zanini - Nonlinear Analysis: Real World Applications, 2015 - Elsevier
This paper focuses on (incomplete) rate-independent damage in elastic bodies. Since the
driving energy is nonconvex, solutions may have jumps as a function of time, and in this …

Rate-independent damage in thermo-viscoelastic materials with inertia

G Lazzaroni, R Rossi, M Thomas, R Toader - Journal of Dynamics and …, 2018 - Springer
We present a model for rate-independent, unidirectional, partial damage in visco-elastic
materials with inertia and thermal effects. The damage process is modeled by means of an …

On the quasistatic limit of dynamic evolutions for a peeling test in dimension one

G Lazzaroni, L Nardini - Journal of Nonlinear Science, 2018 - Springer
The aim of this paper is to study the quasistatic limit of a one-dimensional model of dynamic
debonding. We start from a dynamic problem that strongly couples the wave equation in a …
