This article deals with a non-classical scale transition devoted, in the long-run, to prediction of nonlinear mechanical behavior energetic composites. A geometrical and kinematical schematization microstructure is defined as conspicuous starting point for further localization-homogenization procedure. Thus, salient information on morphology some intraphase heterogeneity are taken into account. The first results obtained finite strain context three-dimensional periodic compared element solution. Furthermore, ability methodology deal viscohyperelasticity direct manner illustrated. significant step towards efficient mastery viscoelastic aggregates, whose inherent characteristic lies space/time local interactions relative “long-memory” effect.
