Momentum Transfer from Explosion-Driven Shock Waves to Tree Stems

Abstract

The successful and efficient utilization of bombs for clearing HLZ's can be greatly enhanced by the use of techniques for predicting the dimensions of clearings that can be obtained with various bomb yields in various kinds of forests. The output of an analytical solution that is to be useful in comparing explosive clearing devices during the design stage or in evaluating the effectiveness of a given device in a given forest environment must include tree remnant height with respect to horizontal distance from the explosion center. Analytical techniques for predicting tree stem failure as a function of wood strength properties, stem diameter, and shock wave (front) characteristics are presented.
