Abstract

"An experimental method has been developed for determining the tensile and other physical properties of metals under high loading rates. Experimental equipment was designed, fabricated and tested. It was desirable to keep the equipment simple and inexpensive so that it could be used by operators Lacking experience in electronics and high-speed photography which are required for some of the more sophisticated methods now in use. The energy for pulling the specimens is supplied by smokeless gun powder. The firing of a cartridge into a closed cylinder with movable piston accomplishes the breaking of the specimen. A record of the time, pressure trace is obtained with a Polaroid camera and an oscilloscope. The firing of the cartridge is accomplished with an electric bridge. This permits synchronization between the oscilloscope triggering circuit and the cartridge firing. The primary purpose of this research work was to develop a method for testing under high rates of strain rather than to gather specific data on specific specimens. However, five different materials were employed, and data is presented"-- Abstract p. i
