Shock attenuation experiments using a Hopkinson bar method : summary of experimental results

Abstract

Close-in attenuation of the pressure wave from a detonation is desirable in several applications. Porous materials are often assumed to have good shock damping properties. In this report an experimental set-up using a Hopkinson bar to test the attenuation of various materials is described. Experiments with several materials have been carried out and are documented here. Analysis of the results will be presented separately in a future document.

I mange sammenhenger er det ønskelig å kunne dempe sjokkbølger. Porøse materialer antas å ha gode sjokkdempende egenskaper. I denne rapporten beskrives et eksperimentelt oppsett med en såkalt Hopkinson Bar for å teste sjokkdempningsegenskapene til forskjellige materialer. Deretter dokumenteres eksperimenter utført med dette oppsettet for en rekke materialer. Analyse av resultatene dokumenteres separat i en fremtidig rapport.
