Abstract
In the present paper on the basis of asymptotically confirmed hypotheses method, depending on the values of dimensionless physical parameters, dynamic models of micropolar elastic anisotropic (orthotropic) thin bars with free fields of displacements and rotations, with constrained rotation and with “small shift rigidity” are constructed. Transverse shift and related deformations are completely taken into account in the constructed models of micropolar bars. On the basis of these models problem of determination of frequencies of free oscillations of hinged-supported micropolar orthotropic elastic thin bar is studied.
