Uniform asymptotics for a family of degenerating variational problems and error estimates in homogenisation theory

S Cooper, I Kamotski, VP Smyshlyaev - arXiv preprint arXiv:2307.13151, 2023 - arxiv.org
We study an abstract family of asymptotically degenerating variational problems. Those are
natural generalisations of families of problems emerging upon application of a rescaled …

Multiphase homogenized diffusion models for problems with several parameters

GV Sandrakov - Izvestiya: Mathematics, 2007 - iopscience.iop.org
We deal with the homogenization of initial-boundary-value problems for parabolic equations
with asymptotically degenerate rapidly oscillating periodic coefficients, which are models for …

Torsion effects in elastic composites with high contrast

M Bellieud - SIAM journal on mathematical analysis, 2010 - SIAM
We establish a homogenization result and a corrector result for a vibration problem of
elasticity. We assume that the data depend in a periodic way on a small parameter ε. We …

[PDF][PDF] A variational approach to double‐porosity problems

A Braides, VC Piat, A Piatnitski - Asymptotic Analysis, 2004 - Citeseer
In this paper we outline an approach by Γ-convergence to some problems related to 'double-
porosity'homogenization. Various such models have been discussed in the mathematical …

Homogenization of discrete high-contrast energies

A Braides, V Chiadò Piat, A Piatnitski - SIAM Journal on Mathematical Analysis, 2015 - SIAM
This paper focuses on deriving double-porosity models from simple high-contrast atomistic
interactions. Using the variational approach and Γ-convergence techniques we derive the …

Two-scale homogenization for a general class of high contrast PDE systems with periodic coefficients
