title = "Measurement of Cone-Cylinder Deceleration in Sand",
abstract = "Cone cylinders measuring 25 mm in diameter and weighing 108 g were shot into dense silica sand beds, mostly at 200 m/s, using a vertical-firing 75-mm diameter compressed-air gun. Velocity-time records were obtained with a multichannel homodyne photon Doppler velocimeter (PDV). Good values for deceleration were obtained below about 150 m/s. In terms of Poncelet parameters, the Poncelet drag coefficient for dense sand was bivalued, being 2.0 above about 80 m/s and 1.5 below that, and was unaffected by saturation. It was about 1.0 for medium dense sand. Values of the R term were 250–450 kPa.",
