S. Challal, HOMOGENIZATION OF INSTANTANEOUS MEMORY PR OBLEM IN VERY FINELY PERFORATED MEDIUM, Comptes rendus de l'Academie des sciences. Serie 1, Mathematique, 317(2), 1993, pp. 149-154
We study the homogenization of a perforated area with tiny, holes in w
hich lies a viscous compressible and barotropic fluid. The problem is
of elasticity type with instantaneous memory. In the asymptotic proble
m, a long memory phenomenon on appears. We study the case of spherical
holes (with radius a(epsilon) much less than epsilon) periodically di
stributed in the whole volume.
