Blast Wave Yields for an Explosion
NAVAL WEAPONS CENTER CHINA LAKE CA
A blast wave overpressure-time history contains voluminous data which can be greatly simplified by converting them into equivalent yield. This calculation requires two independent parameters, usually chosen from measurements on peak overpressure, impulse, standoff distance, or travel time. Representative computations are described. Concurrence among the results of these for a particular explosion indicates a simple explosion situation and reliable data divergence implies some effect such as focussed blast, or perhaps errors in measurement. All such information is useful in evaluation of blast wave data, and can contribute to our understanding of explosion phenomena.
