Transmission of shocks along thin-walled tubes

Experiments have been fired in which stainless steel tubes of internal diameter 50 mm, ranging in thickness from 2.5 mm to 7.5 mm and of two lengths, 40 mm and 80 mm, are shocked at one end by an explosive charge. The other end of the tube is positioned in contact with a steel anvil. Before it reaches the anvil, the transmitted stress pulse attenuates to an elastic-plastic wave. The transmission of the stress pulse along the tube and into the anvil is monitored (a) by strain gauges on the surface of the tube and (b) by pressure gauges positioned at the input and output ends of the cylinder and embedded in the steel anvil. The experimental data is compared with the ALE code CORVUS. The timing and shape of features observed within the calculated wave profiles match those in the gauge data
