Fading memory effects in elastic-viscoelastic composites

We study the macroscopic behavior of an elastic-viscoelastic mixture, in the non penodic case The oscillating problem présents an elastic term and a short memory term At the macroscopic level a long memory term, of the convolution type, also appears The mam re suit consists in establishing the limit équation and charactenzing Us coefficients in terms of the oscillations of the domains occupied by each component of the mixture
