Analysis of a Generic Warhead Part I: Experimental and Computational Assessment of Free Field Overpressure

Abstract

Experimental and numerical results are presented for the free field blast generated by a 7.8 kg cylindrical charge of Composition B high explosive. In the experiments, overpressure and shock front time of arrival measurements have been recorded. Overpressure measurements in the far field provide pressure histories at discrete locations. Peak overpressure in the near field is calculated from time of arrival measurements. In addition, the numerical model was used to generate overpressure histories and two-dimensional contour plots of the blast wave.
