MEASUREMENT OF STRONG SHOCK PRESSURE

This paper deals with measurement of a strong shock pressure like an i mploding detonation of over 1 GPa which cannot be measured directly wi th currently, available commercial pressure transducers. After the tra nsfer functions of three kinds of materials were measured using a shoc k tube, Teflon was selected as a shock absorber As an example of press ure beyond the limit of the pressure transducer we tried to measure pr essure at the center of an imploding detonation. From this measurement , we could estimate the pressure peak of about 1.7 GPa.
