Abstract

It is widely known that the result of a chamber pressure measurement is dependent upon the used measurement technique. This work compares pressure measurements made with two different types of piezoelectric transducers (C.I.P. and SAAMI) to measurements made using copper crushers. Dynamic material characterization followed by finite element modeling of the dynamic compression of the copper crusher inside the chamber was used in an effort to elucidate on the different peak pressures determined with these different measurement techniques. Although the finite element model validated the conversion table supplied with the copper crushers, the results did not permit to make any statistically relevant conclusions on the accuracy of the different measurement techniques.
