Copper units of pressure - Wikipedia
The amount of deformation is compared to the amount of crushing produced by different pressures in pounds per square inch. Copper cylinders are used at high pressures, such as are generated by most handgun and rifle cartridges, and lead cylinders are used for low pressures such as are generated by shotgun shells. The crusher gun has a hole in the chamber that is linked to a piston, and upon firing, …
Nonlinear Material Behavior Analysis under High ...
The deformation of copper crushers has also been simulated to compare its deformation with real time firing. The results indicate erratic behavior for chamber pressure by copper crusher as per standard deviation and relative spread and thus prove piezo sensor as more reliable and consistent mode of peak pressure measurement.
Rimfire Firing-Pin Indent Copper Crusher (part 1) | 2017 ...
Both variations of the copper-crusher measuring system (to measure barrel pressure and firing-pin impact force) rely on mechanical deformation of a copper bar. In order to provide consistent results, the copper used in the crusher must have very specific yield stress, elastic modulus (Young’s modulus) and other physical properties (Table 1).
Copper crushers - dynamic calibration in the laboratory
Copper crusher gauges are the traditional means to routinely determine peak pressures in large caliber weapons. Most attractive in this method is its simplicity in use. Questionable is the precision in reading the pressure in view of the cumbersome gauge calibration practice which is prone to errors, especially in the low temperature regime.

Metallic Cartridge Chamber Pressure Measurement
In this crusher chamber is placed a very precisely manufactured piece of copper. When the gun is fired the copper pellet is crushed (deformed) by the pressure to some degree. The amount of this deformation is then precisely measured and a very standardized indication of pressure is determined.

Tables supplied by the manufacturer of the copper crushers are used to convert the deformation into relative values called "copper units of pressure," commonly...
BALLISTIC PRESSURE SENSOR REFERENCE GUIDE
The resulting pressure acting on the piston forces the copper crusher into a permanent deformation. The crusher is removed and carefully measured. Tables supplied by the crusher manufacturers are used to convert the deformation into a relative value, called copper units of pressure (commonly referred to as “cups.”)
1. Introduction - Hindawi Publishing Corporation
The deformation achieved via copper crusher varies nonlinearly as per theory and the same becomes more and more evident for higher values of pressure. The results for current research however do not show a clear difference between deformations which is conclusive enough for nonlinear behavior of copper material.
