TSALIS, DimitriosBONNAY, KevinCHATZIGEORGIOU, GeorgeCHARALAMBAKIS, NicolasRésumé
In this paper, the analytical solution of the multiple - step homogenization problem for multi - rank composites with generalized periodicity made of elastic materials is presented. The proposed homogenization scheme is combined with computational homogenization for solving more complex microstructures. Two numerical examples arepresented, concerning a “chevron” composite and a wavy fiber reinforced composite.
