manufacturing of copper crusher for measuring of chamber pressure

Until the mid 1960's the only method commonly used for measuring chamber pressures was the copper crusher. Basically, a hole is drilled in the chamber of a firearm and a crusher chamber is attached to that hole. In this crusher chamber is placed a very precisely manufactured piece of copper.

    Nonlinear Material Behavior Analysis under High

    Copper crushers and piezoelectric sensor methods both have their pros and cons for chamber pressure measurement. Copper crusher technique is simple enough to obtain a rapid estimation of the peak pressure in ammunition testing but it has drawbacks for being of limited accuracy and only gives the peak pressure . Similarly, for higher pressures the deformations noted are lower in comparison to that obtained through piezoelectric sensors due to nonlinear variations which are observed in copper ...
