Seismic radiation from an explosive column

Webwave amplitudes, and (c) the effect of the borehole and other man-made features on the nonisotropic seismic radiation. The current project-is an extension of the previous experimental study (Contract No FA9453-16-C-0021) intended to isolate and quantify the effects of the individual explosive properties on seismic amplitudes and spectra.

WebApr 9, 2024 · A blast expansion cavity is used to establish a relationship between the explosive properties and amplitude frequency of blast-induced seismic waves. In this model, the dominant frequency and amplitude of blast-induced seismic waves are mainly influenced by the initial pressure and the adiabatic exponent of explosives in the same medium. WebIn this model, the dominant frequency and amplitude of blast-induced seismic waves are mainly influenced by the initial pressure and the adiabatic exponent of explosives in the same medium. The dominant frequency increases with the decreasing initial pressure or the increasing adiabatic exponent. kpop and mental health https://uptimesg.com
