Abstract
A new technique to heat metallic specimens, in split-Hopkinson-bar experiments, is presented. The heating is achieved with induction coils surrounding the specimen. The main advantages of this technique are (1) a relatively fast heating rate, (2) localization of the heated volume, and (3) heating achieved without touching the specimen. Experimental results for several metals, in terms of high strain-rate stress-strain curves at elevated temperatures, are presented and discussed.
