Responses of the aluminum multilayer composite to dynamic loading are described by the relaxation model of plasticity. Relations between the rate sensitivity of the multilayer composite, parameters of the dynamic loading and the strain rate sensitivity of its components are established. It is shown that estimates of the rate sensitivity turned out to be higher for GLARE composite in comparison to the rate sensitivity estimates for its component of Al 2024-T3 sheet metal.
