| Popis: | Experiments of shock wave propagation performed on 9% and 17% porous aluminum are presented and analyzed. The originality of the plate impact set-up and its associated metrology (VISAR interferometry and PVDF piezoelectric gages) exhibits also the influence of local physical mechanisms on shock wave propagation in porous aluminum. More, the variations observed between the rise times of shocks seem to point out a preponderance of the dynamic effects (inertia or strain rate) over the material behavior. This point is confirmed by comparing quasi static and dynamic responses of porous aluminum. |
