Description

Recently, the high speed compression test has been carried out in order to elucidate the mechanism of dynamic consolidation. However, detailed studies for the dynamic property of sensors used for this kind of test equipment has not been performed. The dynamic property of load cell transducers is examined using a multiple reflection theory. Next, the analytical method of two-point stress measurement applied to the theory of one dimensional wave propagation is studied for the dynamic response of the load cell transducer experimentally. This study shows that the use of load cell transducers should have the restriction for the high speed test because of its low sensitivity to the dynamic test.
