Abstract: The dynamic viscosity and characteristic relaxation time at various scale-structural levels of deformation of a shock-loaded medium are determined using concepts of multilevel solid-state mechanics. The notion of the quasi-time fractal dimension is introduced and used to calculate the indicated characteristics. Computational-experimental data for the viscosity and relaxation time are given for three materials:M2 copper, AMg6 aluminum base alloy and Armco iron.

Keywords: dynamic viscosity, relaxation, structural level, fractal dimension.
