Abstract

A new facility for dynamic material testing using a traditional Kolsky bar with the addition of controlled electrical-resistive pulse heating has been established at the National Institute of Standrds and Technology (NIST). Dynamic stress-strain data have been obtained for several metal samples at high strain rates (current capability is approximately 500 s^-1 to 10,000 s^-1). By resistively heating the samples prior to impact (current capability is for sample temperatures up to approximately 1000 ?C) dynamic stress-strain data at elevated temperatures can be obtained. These data are being generated to assist in the simulation of machining processes.
