Preliminary studies on response of longitudinal and lateral gauges for shock wave

In this paper, different dynamic responses of longitudinal and lateral gauges in PMMA and anti-shoot ceramic were investigated by 1-D plate flying tests and theoretical analyses. The experimental results indicate that the lateral stresses can be calculated directly from the piezoresistance expression calibrated by longitudinal stresses with the method of strain remedy by constantan gauge as the lateral stresses in anti-shoot ceramic are measured. But the lateral stresses in PMMA can not be determined by this method.
