Abstract: The study investigates the dynamics of a microsphere with a double-layered shell embedded in a polymer matrix under the influence of a shock wave. The mechanisms of deformation and failure of the microsphere's shell, as well as the impact of the polymer matrix properties on the transmission of shock loading, are examined. Using computer models in a series of computational experiments, the processes of shock wave propagation through the composite material were analyzed, taking into account the differences in the mechanical properties of the shell layers and the polymer medium. It is demonstrated that the double-layered shell structure facilitates effective energy absorption from the shock impact and the formation of filamentary structures. The results of the study can be applied to optimize the properties of composite materials used under dynamic loading conditions, such as shock waves.

Keywords: microsphere dynamics, shock wave, shell deformation, composite material, filamentary structures, optimization of composite materials.
