Comportement des matériaux cellulaires sous impact et de panneaux sandwichs sous perforation dynamique

Abstract : In this PhD, we studied, int the first part, shock enhancement of cellular materiels(foam, honeycomb and hollow spheres) under impact loading. First, an original testing procedure with the SHPB to study shock enhancement effet in such materiels followed by digital image correlation and nunerical simulation are introduced. In the second part, new perforation testing technique using a long thin instrumented Hopkison bar is proposed ineverse perforation. The present method makes it possible to compare directly impact piercing force dispacement curves with the static ones.
