Abstract

"A capacitive transducer was developed for measuring the free surface motion in Hydrostone blocks loaded by an explosive plane wave generator approximately one foot from the specimen. The charge to specimen distance was adjusted to produce a single spall, the position of the fracture being noted on the recovered specimen. The longitudinal wave velocity in each specimen was determined by the ultrasonic pulse technique before each shot. From the above measurements the stress, strain and strain rate at the point of fracture were determined. An attempt was made to determine the actual fracture time with imbedded [sic] conductive graphite rods, however it was not successful. It was concluded that the size of the specimen (6 by 6 by 4 in.) was too small for meaningful measurements of dynamic strength since the explosion pulse was found to be longer than twice the length of the specimen"--Abstract, page ii.
