Abstract Scope |
A significant body of work has developed for the case of dynamic compression response of polycrystalline and multi-phase alloy microstructures. The experimental studies have been augmented by constitutive laws that describe the flow behavior under these high strain rate, high pressure loading conditions. Composite media with constituents that do not chemically interact with each other have been less frequently studied, though they have importance where multi-functionality can only be introduced through artificial means. We will compare the volumetric response of composite microstructures using free-surface velocimetry measurements. As an analog with multiphase alloys, the effects of a length scale encoded in particle volume fraction and size will be elucidated. This will be discussed in the context of processes such as internal wave reverberation, multiphase drag, and particle-particle force transfer that determine the rate of compression in a shock deformed particulate composite. |
