Abstract
An investigation is made of the stress system set up by an explosive detonating in contact with a metal surface. An extrapolation from data on the compressibility of steel and lead leads to the conclusion that the shock wave set up by the detonation has an initial velocity in steel which is less, and an initial velocity in lead which is greater, than the velocity of plane elastic waves. The time taken by the fastest pulse to penetrate various lengths of steel and of lead has been measured experimentally, and the results confirm that the plane elastic waves move more quickly for steel; while for lead the shock wave before damping has a velocity well in excess of that of the elastic waves.
