| Abstract: | A method for determining the stiffness and rheological characteristics of composite materials, based on minimizing the mismatch
of experimental data and the results of numerically modeling nonstationary deformation processes in shells ofrevolution made
of composites materials, is presented. This approach is used for analyzing the damping characteristics of chaotically reinforced
and cloth-reinforced composites.
