Measuring Strength at Ultrahigh Strain Rates
The use of uniaxial strain ramp loading experiments to measure strength at extremely high strain rates is discussed. The technique is outlined and issues associated with it are examined. Results for 6061-T6 aluminum are presented that differ from the conventional view of strain rate sensitivity in aluminum alloys.
