BEHAVIOR OF PLEXIGLAS UNDER SHOCK LOADING BY A TETRYL DONOR,
Abstract
Details of the disturbance in shock loaded Plexiglas were observed with a smear camera and with the Jacobs framing camera; both exploding wire and diffuse lighting were used. Records obtained by the various techniques are compared; it is found that several techniques should be used to obtain the most complete information about the observed phenomena. Experiments to establish pressure as a function of distance in a 5.08 x 5.08 x 12.7 cm rectangular parallelopiped of Plexiglas, shocked by a tetryl donor, result in a shock velocity (or pressure) vs. distance curve, within experimental precision, the same as that for a Plexiglas rod of 5.08 cm diameter. Shock front curvature and the average unloading rate between shock and break-up, each shows a discontinuity when plotted as a function of length of shock path through the material. The point of discontinuity is at 2.54 cm, the radius of the shock loaded surface, and is attributed to the arrival and intersection of the lateral rarefactions at the axis of the block. (Author)
