UNIAXIAL-STRAIN WAVE-PROPAGATION EXPERIMENTS USING SHOCK-TUBE LOADING.
Abstract
A technique for studying uniaxial strain pulse propagation is discussed. The face of a disk-shaped sample is loaded uniformly with step-function pressure by reflection of a gasdynamic shock wave. The effect of propagation through the sample on the step pulse is observed by use of measurements of the velocity of the sample's rear surface made with a capacitive transducer. Data are presented for several materials. The technique is advantageous for study of pulse dispersion mechanisms such as bulk viscoelasticity and heterogeneous microstructure. (Author)
