Abstract

This research examines the resistance of metal sandwich plates with corrugated core subjected to impulsive loading over central patch, in which effects of the low-density polymeric foam filling the interstices of the corrugated core on dynamic response of sandwich plate are studied to ascertain the enhancement of sandwich plate under impulsive loading. The face sheets and corrugated core are made of the same metal materials. The resistance of the metal sandwich plates with foam-filled cores is compared to that of the metal sandwich plates with unfilled core with the same weight. The results of comparison show that the foam-filled core does not make the overall deflection decrease compared with empty core, but it can make the sandwich plate achieve multifunctional advantages. The membrane method is employed to predict large deflection response of metal sandwich plates with foam-filled and unfilled cores under impulsive loading over a central patch. The theoretical predictions agree well with finite element (FE) results of sandwich plates with foam-filled and empty cores.
