ABSTRACT
Experiments have been carried out to determine the effect of strain rate and temperature
on the tensile behavior of a 6061-T6 aluminum alloy. All tests were performed using a
tensile split Hopkinson pressure bar at a nominal strain rates in the range of 100 to 500 s-1
and initial temperatures between 80 oC and 250 oC. A heating system was used which
was capable of raising the temperature of the test specimen rapidly while the apparatus
remains at room temperature. Using experimentally determined flow curves, the effect of
the strain rate and the temperature on the tensile properties was predicted. The results
showed that the flow stress, tensile strength and elongation percent are controlled by the
strain rate and the temperature.
