Compression and Shear Wave Propagation in Plain and Filled Elastomers.
Abstract
Experimental results from several research tasks designed to address fundamental issues related to the shock response of energetic materials are summarized and discussed. Shock response of a recently synthesized energetic elastomer (BAMO/THF) and a composite (CdS/BAMO:THF) have been determined experimentally. Bulk and shear moduli, and viscosity of the elastometer were measured for different shock compressions. The elastomer behaves as a viscous fluid and no thermal decomposition was detected. The composite results can be modeled using a simple mixture model. The experimental results show that the Cadmium Sulfide particles experience a nearly hydrodynamic compression and no strength effects appear to be present. The measured end states are in agreement with the Wurtzite to rock salt transition observed in hydrostatically compressed CdS. Experimental techniques have been developed to examine shock induced phase transformation in CdS single crystals. Preliminary results suggest that prior to transformation the CdS remains elastic.
