Copper units of pressure Wikipedia

Copper units of pressure or CUP, and the related lead units of pressure or LUP, are terms applied to pressure measurements used in the field of internal ballistics for the estimation of chamber pressures in firearms.These terms were adopted by convention to indicate that the pressure values were measured by copper crusher and lead crusher gauges respectively.

Nonlinear Material Behavior Analysis under High

The nonlinear deformation rate of copper at high pressure measurements causes actual readings from copper crusher gauge to deviate from true pressure values. Comparative analysis of gun chamber pressure was conducted for 7.62 × 51 mm ammunition using Electronic Pressure, Velocity, and Action Time (EPVAT) system with piezoelectric

Correlating PSI and CUP

chamber pressure was the copper crusher method. Up until that time, what we now call CUP was commonly known by two different names: CUP and PSI. The two were used practically interchangeably. Of course, this use of PSI was incorrect. It wasn't much of a problem until piezoelectric and strain gauge systems became commonly available. These

Internal Ballistics

Piezo (PSI) and strain gauge (PSI) are not directly relatable to copper crusher (CUP) due to the differences in the sensitivity of the copper crusher versus the other methods used to measure the pressure. However, new statistical data analysis suggests that for most cartridges ANSI/SAAMI Maximum Average Piezo (PSI) and Maximum Average copper crusher (CUP) taken in a "standard" barrel can
