PRODUCTION OF STRONG SHOCKS IN PLASTICS BY ULTRA-SHORT IMPULSIVE LOADING
Abstract
Pressures in excess of 100 kb can be produced in plastics by the impact of high velocity thin plates. These plates, mainly Mylar and Lucite in the range of 0.01 to 0.6 cm in thickness and areal dimensions to 7.5 cm square, have been accelerated by an exploing foil technique. Plates impacted at velocities approaching 500,000 cm/sec have been used for the study of material dynamics at high transient pressures. Pulse lengths in the submirosecond-to-fewmicrosecond region can be produced by this technique, and the variation of the strength of materials with pulse length can be determined. A description of the technique and methods for analyzing the data are presented, including an explanation of the construction of the transducer and photographic equipment used in the laboratory for the velocity determination. Various applications of this technique are also given. (Author)
