ON THE RESPONSE OF SHOCK-SPECTRUM GAUGES

Abstract

An approximate analysis for the maximum response of a buried, simple harmonic oscillator (shockspectrum gauge) to a blast wave moving along the surface is carried out on the assumption of essentially one-dimensional, elastic wave propagation from surface to gauge. The result is of the form q sub m = (p sub m T/rho c) F sub m (omega T), where q sub m denotes maximum displacement, p sub m peak overpressure, T duration of positive pressure, rho soil density, c dilatational wave speed, omega natural frequency of oscillator, and F sub m the maximum value of the convolution of the pressure signature.
