ABSTRACT
Corrugated-core sandwich panels are efficient protective structures that can absorb blast/impact energy through plastic deformation. A relatively non-expensive folding technique is used to manufacture the core to different topologies. Literature survey revealed that the dynamic response of metallic trapezoidal corrugated-core sandwich panels subjected to near-field/contact detonations has not yet been thoroughly investigated. Hence, the aim of this study is to examine, with field tests, if trapezoidal core sandwich panels can protect a pre-cast concrete target from adjacent/contact detonations. The performance and damage behavior of two pre-cast RC slabs were assessed with and without aluminum sandwich panels. The two slabs were subjected to 4 detonations ranging from close to contact explosions. The study concludes that the implemented sandwich panel is not suitable for near-field or contact detonations and might be a protective solution for far-field explosion scenarios.
