EFFECTS OF GEOMETRY ON FLASH THERMAL DAMAGE,

Abstract

A group of specimens have been prepared and exposed at various ranges from two atomic explosions. These specimens were designed to demonstrate the effect of target geometry on the thermal damage. It is shown that specularly reflecting cavities can concentrate the radiant energy and assist in increasing thermal damage to wooden specimens. Thermal properties of the backing material of mahogany specimens as thick as 1/8-in. can modify the extent of thermal damage to the specimen. Under mild radiant exposure conditions a dark specimen shows greater damage than a more reflectant specimen. This effect of specimen color on resulting thermal damage disappears under severe exposure conditions. (Author)
