| Abstract: | A method is proposed for determining the stiffness and rheological characteristics of composite materials, which is based
on minimizing the disagreement between experimental data and results of numerical simulations of deformation of hemispherical
shells under explosive loading. The damping characteristics of randomly reinforced polymer materials are analyzed with the
use of this method.
