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

The gas check, piston, and copper crusher are installed and retained with the thumb screw. When fired, the gases vent out through the drilled hole and expand the gas check into the piston hole, forming a seal. The resulting pressure acting on the piston forces the copper crusher into a permanent deformation. The crusher is removed and carefully
