Multiscale analysis of anisotropic materials with hexagonal microstructure as micropolar continua
This work discusses the advantages of micropolar theory in modeling anisotropic composite materials with microstruc-ture. A homogenized constitutive model starting from a representative volume element is proposed in order to find an equivalent continuum. Classical (e.g., Cauchy of Grade 1) continua are not always suitable to accurately approximate the behavior of such composites because no size effects, nor lack of symmetries in strain and stress, can be taken into account.
