This paper presents a new dynamic calibration method for crusher pressure gauges used in artillery test firings. The calibration method is based on the measurement of the plastic deformation behavior of the crusher elements in the laboratory completely isolated from test firings and measurements by reference pressure transducers. The validity of the calibration model developed is verified by comparison with the pressure records measured in artillery test firings. It was found that the calibration method developed is also suitable for the high load levels and strain rates present in tank firings.
