The Effects of Strain-Rate and Strain-Rate History on the Mechanical Properties of Several Metals.
Abstract
Constant and variable strain-rate test data are reported for 1100-0 and 1199-0 aluminum, AISI 1020 steel, and commercially pure 50-A titanium in shear. Torsion tests on thin-walled tubes covering a range in shear strain-rates from 0.0001 to 25/sec. up to 10 percent strain show that pure aluminum shows very little rate sensitivity while steel and titanium are noticeably rate sensitive. Variable rate tests show that subsequent dynamic loading on a statically prestrained specimen causes an increase in the flow stress in steel and a decrease in the flow stress in titanium. (Author)
