ACCELERATION OF THIN PLATES BY EXPLODING FOIL TECHNIQUES
Abstract
A technique for the acceleration of thin plate to high velocities by exploding foils was dev loped. T ese plates, primarily Mylar and Lucite with areal dimensions up to 3 in. x 3 in. and thicknesses from a few mils o .25 in. are used to produce a high-impul short-time loading of materials for the purpose of material dynamics at high pressures. Velocities up to 5 0,0 0 cm/sec were achieved. A brief description of equipment including the cap ci or system, cameras, backlighting, etc., is given. A detailed description of the construction of the transducers and the characteristics of different types of transducers including such items as the efficiency of energy transfer, velocities obtainable, and matching of transducer to the capacitor system are given. Methods of velocity determination are described, and photographs of these high velocity plates re achieved.
