Analytical Blast Model Formulation With Computer Code

Abstract

Overpressure time history data from warhead blast experiments yield peak overpressure P as a function of spatial position. Dr. Owen Litt has proposed a model for P based on the peak overpressure characteristics of a bare spherical charge. The direction independent peak overpressure function for a bare spherical charge is modified to have nonspherical level surface structure by specifying surfaces of constant peak overpressure. This introduces a directional component into the model. In this report, the original formulation is refined and generalized and a mathematical model and computer code are presented to evaluate the function. Such a computational device is required for model parameter estimation and experiment design.
