From our point of view, this quasi-static calibration does not consider particularly the dynamic behavior of the copper crusher especially required for ballistic dynamic measurements. This might explain the difference of up to 20% in peak pressures between the crusher values and that measured by a piezoelectric pressure transducer, currently ...
