Overall properties for elastic micropolar heterogeneous laminated composites with centro-symmetric constituents

Abstract

In this work, the effective properties of multi-phase periodic laminated Cosserat composite are computed by means of the two-scale asymptotic homog- enization method (AHM). The statements of the local problems and the formu- las of the associated effective properties are explicitly described. In addition, the case of centro-symmetric laminated Cosserat with isotropic constituents is studied and the corresponding effective coefficients are given in terms of the engineering constants. Numerical results for different periodic centro-symmetric bi-laminated Cosserat composites are reported and analyzed.
