The study is conducted using the finite element method with emphasis on Hermiticity, positive definiteness, principle of virtual work and Bloch–Floquet boundary conditions. The periodic boundary conditions are given for both translational and rotational degrees of freedom and for the associated force- and couple-traction vectors. Results in terms of band structures for different material cells and mechanical parameters are provided. © 2019 Elsevier B.V.enghttps://v2.sherpa.ac.uk/id/publication/issn/0165-2125info:eu-repo/semantics/articleBoundary conditionsDegrees of freedom (mechanics)Dispersion (waves)Wave propagationCosseratDispersive mediaMechanical parametersMicropolar elasticityPeriodic boundary conditionsPositive definitenessPrinciple of virtual workRotational degrees of freedomFinite element methodCosserat theorycrystalelasticityfinite element methodnumerical modelwave dispersionwave propagation2021-04-16Guarín-Zapata N.Gomez J.Valencia C.Dargush G.F.Hadjesfandiari A.R.10.1016/j.wavemoti.2019.102406
