Abstract

Many experimental techniques have been developed to determine the compressive strength or flow stress of a material under high strain rate or shock loading conditions [1-3]. In addition, pressure-shear techniques have been developed that allow for the measurement of the shearing response of materials under pressure [4-6]. The technique described is similar to the traditional pressure-shear plate-impact experiments except that window interferometry is used to measure both the normal and transverse particle velocities at a sample-window interface. The velocities are measured using the normal displacement interferometer (NDI) for the normal velocity, and the transverse displacement interferometer (TDI) for the transverse velocity [7].
