Multi-field modeling of a Cosserat lattice: Models, wave filtering, and boundary effects

Vasiliev, A A; Dmitriev, Sergey V; Miroshnichenko, Andrey


Various generalized continuum models are developed to analyze the one-dimensional shear deformations of a Cosserat lattice. The original discrete model and the derived continuum models are applied to the analysis of long- and short-wavelength harmonic waves, localized waves, static boundary effects, and the spectrum stop bands in the wave filtering problem. It is found that the conventional single-field and gradient micropolar models are capable of describing the long-wavelength harmonic and...[Show more]
