Web29 Sep 2010 · Tensile tests are carried out for the aluminum alloys AA1200 and AA3103 at various strain-rates in the range from 10−4 s−1 to 1 s−1. Tests with constant nominal strain-rate and strain-rate jump tests are conducted, and the instantaneous rate sensitivity and the rate sensitivity of strain hardening are investigated. For both materials, the instantaneous … Webdifferent strain rates. The purpose of this study was to determine the strain rate sensitivity and temperature sensitivity of polypropylene and talc-filled polypropyl- ene.
