The Strain-Rate Sensitivity of Irreversible Deformation of the Metallic Multilayer Composite GLARE

摘要

The responses of an aluminum multilayer composite to dynamic loading are described using the relaxation model of plasticity. The relations between the strain-rate sensitivity of a multilayer composite, the dynamic-loading parameters, and the strain-rate sensitivity of its components are established. The estimates of the strain-rate sensitivity are shown to be higher for the GLARE composite as compared to those for the rate sensitivity for its component-Al 2024-T3 sheet metal.
