Abstract

The damage done to structures in air or under water by a charge of mass W exploding a certain distance R away, can in both media be described by the so‐called square root relation, \documentclass{article}\pagestyle{empty}\begin{document}${\rm R} \approx \sqrt {\rm W}$\end{document}. This is better than a simple rule‐of‐thumb, because it implies the physical quantity of an energy density. It is shown that this energy density can also be derived from the product of peak overpressure times impulse for a blast wave in air or a shock wave in water.

## Abstract Simple equations of laser‐induced plasma shock wave motion in air are studied, based on the point blast theory. The theoretical models of the shock wave front evolution characterize two stages of shock wave propagation: the initial formation stage and the free attenuation stage. Due con
