This paper investigates the effect of specimen geometry on the measured dynamic mechanical properties of a high strength sheet steel material derived from tensile testing at 15 m/s on a high speed servo-hydraulic test machine. In this study, stochastic modelling is used extensively to support experimental investigations. The current objective is to develop a tensile specimen design and test procedure, which more closely matches the capabilities of the new IARC high speed test machine, to enable accurate and precise measurement of tensile mechanical properties over a range of strain rates up to 600 s - 1.
