Résumé
We present an other proof of a study of Bellieud and Bouchitte that we expect to be more suitable to treat more general geometrical and physical cases. We consider the homogenization of the quasi-linear elliptic problem
-div sigma(epsilon) = a(epsilon) vertical bar del u(epsilon)vertical bar(p-2) del u(epsilon) on Omega u(epsilon) = u(0) on Gamma(0)
sigma(epsilon) center dot n = g on Gamma(1)
where Omega is a bounded cylindrical open subset of R-3 and 1 < p < +infinity. The fibers occupy a set of thin parallel cylinders periodically distributed in Omega. The conductivity coefficient a(epsilon) is epsilon-periodic and takes very high values in the fibers.
