Blast loading of sandwich panels with thin-walled tube cores

An investigation into the response of a novel sandwich panel under blast loading is presented. Thin-walled tubar members have been used extensively as energy absorbers under impact conditions. The progressive folding mechanism induced by axial crushing of the tubes allows for efficient dissipation of kinetic energy. The present study investigates the use of such tubes as a sandwich core material. Several thin-walled tubes are configured in parallel, between mid-steel fase sheets. A programme of experimental, numerical, and analytical investigations are conducted to characterise the energy absorption properties of the sandwich structure under blast loading.
