Additively Manufactured Granular and Binder Metamaterial's Response To Shock

Homogenous material are created using sucrose crystals 180 μm to 250 μm in size and an ultraviolet sensitive resin manufactured by Anycubic. Mesoscale structures are generated in the samples to research their effect shock waves as they traverse through the target. A single stage light gas gun is utilized in the uniaxial plate impact configuration and a photo doppler velocimetry system (PDV) to perform several experiments each focusing on various wave interactions in the materials. The material's physical structure and material properties mimics that of Plastic Bonded Explosives while remaining inert, therefore allows insight into the physical response short of chemical excitation of these granular and plastic materials. CTH simulations are conducted cohesively with each experimentation setup and compared with experimental results to construct more accurate models for the materials.
