Аннотация: Within the framework of linear micropolar theory of elasticity, mathematical model of multilayered cylinder shell is considered. To analyze multilayered structure of the shell, the layer-wise approach is applied. For each layer, the approximations of displacements and rotations together withthe averaging procedure in the thickness direction are applied. The governing equations of the theory are written in a thermodynamically consistent form of the energy conservation laws. For numerical modeling of wave propagation in micropolar shells, the algorithm based on the splitting method incombination with monotone ENO-scheme and Crank-Nicolson scheme is proposed. The computation resultsof dynamic problems on the action of instant concentrated external load are shown for media with various types of microstructure particles.
