DETERMINATION OF ELASTIC PROPERTIES OF PISTON GAUGES USING THE STRAIN GAUGE METHOD
Abstract
Applicability of strain gauge measurements to the determination of Young’s modulus and Poisson’s ratio of pressure-measuring piston-cylinder assemblies is studied. The method is qualified by comparing the results of the strain gauge measurements with those obtained for the same tungsten carbide samples or materials using the resonance vibration and ultrasonic pulse-echo-superposition methods. The elastic constants of the pistons of two piston-cylinder units used at the PTB for the realisation of the pressure scale up to 1 GPa are determined.
