(i) Nonlinear behavior of copper crusher gauge material parameters at high pressure
Pressure measured by copper crusher gauge is always less than the true pressure due to the following reasons:
Crusher gauges were used to measure gas chamber pressure as commonly available standardized method till 1960s .
In our experimental study the chamber pressure was measured by the two different techniques (crusher gauges and piezoelectric sensors) for the "ammunition type 7.62 x 51mm." This research will try to give an insight into the following knowledge gap areas for "ammunition type 7.62 x 51 mm" not explored previously:
(iii) Similar caliber ammunition type "7.62 x 51 mm" used to explore the possibilities of error in crusher gauges from different ordnance manufacturers, that is, NATO standard ammunition versus non-NATO ammunition
(iv) Another prime objective of cost benefit analysis for copper crusher gauges with piezoelectric sensors also not done by other researchers previously.
