Stochastic homogenization of fractional obstacle problems

Francesco Deangelis, Matteo Focardi, Caterina Ida Zeppieri

We prove a stochastic homogenization result for a class of \emph{nonlinear} and \emph{nonlocal} variational problems in domains with many small randomly distributed (bilateral) obs…

Homogenisation of phase-field functionals with linear growth

Francesco Colasanto, Matteo Focardi, Caterina Ida Zeppieri

We propose a first rigorous homogenisation procedure in image-segmentation models by analysing the relative impact of (possibly random) fine-scale oscillations and phase-field regu…

Homogenisation of nonlinear Dirichlet problems in randomly perforated domains under minimal assumptions on the size of perforations

Lucia Scardia, Konstantinos Zemas, Caterina Ida Zeppieri

In this paper we study the convergence of integral functionals with -growth in a randomly perforated domain of , with . Under the assumption that the perfora…

Stochastic homogenization of degenerate integral functionals with linear growth

Matthias Ruf, Caterina Ida Zeppieri

We study the limit behaviour of a sequence of non-convex, vectorial, random integral functionals, defined on , whose integrands satisfy degenerate linear growth conditions…

Gradient damage models for heterogeneous materials

Annika Bach, Teresa Esposito, Roberta Marziani +1

In this paper we study the asymptotic behaviour of phase-field functionals of Am brosio and Tortorelli type allowing for small-scale oscillations both in the volume and in the diff…

Phase-field approximation of functionals defined on piecewise-rigid maps

Marco Cicalese, Matteo Focardi, Caterina Ida Zeppieri

We provide a variational approximation of Ambrosio-Tortorelli type for brittle fracture energies of piecewise-rigid solids. Our result covers both the case of geometrically nonline…
