The effect of strain rate on the dynamic strength of certain materials was investigated. Materials tested were cold-rolled steel, six aluminum alloys, six titanium alloys. uranium, and lead. Each material was tested at strain rates of 10/sup -5/, 10/sup -4/, 10/sup -2/, and 10/sup 2/ in. per in. per sec . The total energy absorbed in the specimen, the difference between original and final gage length, the reduced diameter. the load, and the displacement time were determined. The results are sumruarized in tables and graphs. The increases in yield strength varied from a negligible increase in 5456-0 aluminum to 72.9% increase for 1018 cold-rolled steel. Titanium showed a decrease in elongation with strain rate, while the aluminum and steel specimens showed an increase. (M.C.G.)
