Potential safety concerns drive interest in the development and use of mock high explosive (HE) surrogates that emulate aspects of high explosives. In particular, the processing and thermo-mechanical behavior of compacted pristine and recycled mock HE is studied to further multiscale modeling of mock HE response with exascale computing. In this presentation, we report on recent experimental efforts at the Colorado School of Mines to process mock HE samples and other particle/matrix assemblies, and perform characterization with x-ray computed tomography (CT) and compression testing; including testing at 100 s-1 that is challenging experimentally but was successful. In-situ x-ray CT during quasi-static deformation is also pursued to understand particulate/matrix assembly response under load. The aim is to generate three-dimensional information about particle sizes, morphologies, distributions and thermo-mechanical response to inform modeling of problems involving granular flows, large deformations, and fracture/fragmentation of unbonded and bonded particulate materials, emphasizing mock HE.
