Abstract
ng responses of the material studied were determined through planar impact experiment conducted on a single stage light-gas gun at NPS Impact Physic Lab. Impact velocities ranged from 0.2 to 0.35 km/s. The impactor material for asymmetric experiments was z-cut single crystal sapphire. Diagnostics used included a VISAR system, to measure particle velocities, PZT pins to measure onset of impact, and contact pins to measure impactor velocities and tilt angles. Through this study, dynamic loading response of ceramic Corbit-98 and ceramet tungsten carbide were determined. The Hugoniot Elastic Limit (HEL) of GC-915 was found to be 0.935 GPa and spall strength of approximately 2 GPa was also measured.
