Multiscale homogenization and analysis of anisotropic assemblies as cosserat continua

This work proposes a multiscale analysis of nanocomposites made of hexagonal assemblies. The present nanomaterial is made of irregular concave hexagonal shaped assemblies interacting with elastic interfaces. The homogenization of such irregular units causes anisotropic constitutive properties. The validity of the present homogenization and modeling is verified by comparing the continuum Cosserat model with a discrete model made of physical particles and elastic interfaces. Parametric investigation is also proposed by varying the geometric properties of the nanoparticles by showing the dynamic character of these materials by considering both Cosserat and Cauchy continuum models.
