QUARTERLY REPORT OF TECHNICAL PROGRESS (6TH)

Abstract

The 'mousetrap' type plane-wave generator has been completed. Initial shock tests have been conducted on 2024-T3 aluminum sheet, copper, 70-30 brass, iron, and maraging steel. Accuracy of acceleration measurements to determine strain-rates in an expanding aluminum ring using a streak camera is being checked by recording known motion of a non-radial slit cut in a rotating disk. The correlation between physical properties of metals used in explosive welding and the success of the weld is being investigated. Checkout is continuing on a computer program to calculate strains in a blank formed into a frictionless die. A ring cut in a chevron pattern has proved effective in controlling edge pull- in of explosively formed domes. The chevrons contract to form the ring and engage a weld bead on the rim of the blank to limit the amount of pull-in.
