Gamma(D)-convergence for a class of quasilinear elliptic equations in thin structures

摘要

We study the asymptotic behaviour of the solution of a stationary quasilinear elliptic problem posed in a domain Omega((epsilon)) of asymptotically degenerating measure, i.e. meas Omega((epsilon)) -> 0 as epsilon -> 0, where epsilon is the parameter that, characterizes the scale of the microstructure. We obtain the convergence of the solution and the homogenized model of the problem is constructed using the notion of convergence in domains of degenerating measure. Proofs are given using the method of local characteristics of the medium Omega((epsilon)) associated with our problem in a variational form. Copyright (c) 2005 John Wiley & Sons, Ltd.
