A review of theoretical representations and experimental data on rotational motions
of elements of a continuous medium is given. Description of wave rotational motions is
impossible in the framework of the classical theory of elasticity, but it is allowed within the
scope of generalized continua models (the Cosserat microspolar model, moment and gradient
models, etc.), as well as in the framework of A.V. Vikulin's model, in which the stresses are
described by a symmetric tensor. Physical, geological and geophysical data are given that
confirm both rotational approaches to describing the blocks and plates composing a geomedium
and the existence of rotational waves.
Keywords: microstructured media; the Cosserat theory; rotational waves; geodynamics. |
