Abstract
High strain rate test methods to obtain strain-rate dependent sheet steel tensile properties are considered. A tensile test method for sheet steels was developed to obtain accurate stress-strain data over the strain rate range from 0.001 s-1 to 500 s-1 using a servo-hydraulic test machine and tensile samples instrumented with strain gages. Results on several different automotive sheet steels, including interstitial free (IF), high strength low alloy (HSLA), dual phase (DP), and transformation induced plasticity (TRIP) steels, are presented. The results show that strain rate response differs between the various alloy systems. These results are compared with previously published data on strain-rate dependent steel properties. The importance of stress-strain curve shapes, which depend on alloy system, on energy absorption calculations using areas under stress-strain curves are also described. It was found that comparison of energy absorption between different materials was highly dependent upon the strain limit chosen for the calculations.
