Calibration of the NOL Large Scale Gap Test; Hugoniot Data for Polymethyl Methacrylate

Abstract

ROPERTIESMore accurate calibrations of peak pressure (P) vs gap length (x) are presented for the NOL large scale gap test for both pentolite and tetryl donor charges. These calibrations are derived from particle velocity and shock velocity measurements in the PMMA ATTENUATOR. Particle velocities are recorded by the electromagnetic velocity gage; shock velocities are determined from streak camera records of the progress of shocks through the attenuators. As indicated, both shock velocity (U) and particle velocity (u) were measured. However, the Hugoniot of PMMA was selected by comparing these U-u data, with the low pressure U-u data recently published by Sandia Corporation. The Hugoniot so obtained was used in conjunction with our u- x data to produce the desired calibration curves (P-x).
