Materials in extreme conditions : experimental developments and studies of systems far from equilibrium

Advances to shock wave generation and characterizations techniques are presented. Building upon previous work employing a novel quasi-2D focusing geometry, pressures of at least 100 GPa are achieved on the benchtop at the micron scale. Diagnostics for optical visualization of these generated waves were also refined; an existing single-shot multiframe imaging technique was extended into phase sensitive imaging. These techniques are applied to a range of material systems (energetic materials, brittle solids and biological membranes), pushing them far from equilibrium, and studying their response. While the explosive 1,3,5-triaza-1,3,5-trinitrocyclohexane (RDX), has been used for almost a century, questions remain about its initiation, reactivity, and interaction with shock waves. Very little work has directly addressed the coupling between mechanical deformation and chemistry in this system. Further, the literature to date mostly comprises studies with idealized 1-dimensional waves.
