B3.3 - Calibration or Testing of High-g Shock Accelero¬meters to 100,000 g and Higher

M. Mende & M. Brucke
SPEKTRA has developed a wide range of Hopkinson Bar shock exciters providing shocks from 20 gn (200 m/s2) up to 200,000 gn (2,000,000 m/s2) for calibration and testing purposes. Although shock testing up to 10,000 gn (100,000 m/s2) is commonly performed and well understood, the development of shock exciters for the high shock range required some new ideas to overcome obstacles related to these extreme amplitudes. The discussion will include basic aspects of the theory...
