Abstract
DRDC Valcartier is using a split Hopkinson bar system to conduct high strain rate tests of materials used in the protection of vehicles and personnel against blast and ballistic threats. The original system, built in the beginning of 1990, was modified to better measure the impact velocity. The analytical program was completely redesigned and implemented. To verify the system, Aluminum 6061-T6 was tested at different strain rates. This material is known to be insensitive to strain rate, which allows verification of the results with quasi-static tests. It is also possible to easily find data published in literature that could also be used to validate the high strain results obtained using DRDC Valcartier Hopkinson system. The experimental results were confirmed by modelling the Hopkinson bar system using LSDYNA hydrocode finite element model.
