TL;DR: In this article, an autodyn-based numerical simulation was conducted to investigate the dynamic response of core sandwich panels to air blast loading in an explosion tank considering three levels of blast loading and found that the maximum deflection, core web buckling and core compaction increased as the decrease of stand-off distance.

TL;DR: In this article, effective approaches to enhance the blast resistance of sandwich structures with corrugated cores were developed by adopting three different strategies to fill the spaces within cores with polymeric foam.

TL;DR: In this article, the dynamic response of metallic trapezoidal corrugated core sandwich panels under air blast loading is studied by experimental investigation, which revealed that the deflection and damage level of panel increased with the decrease of stand-off distance.

TL;DR: In this paper, the effect of structural configuration on air blast resistance of polyurea-coated composite steel (PCCS) plates was experimentally evaluated, and failure modes and energy dissipation mechanisms (EDMs) were identified from the stress wave propagation perspective.

TL;DR: In this paper, the effects of material and interface strengths on the failure characteristics of polyurea coated steel (PCS) plates under localized air blast loading were investigated, and the results showed that the kinetic energy of polyuresa fragments significantly contributed to the total energy absorption of polyura backing layer (PBL) that failed due to spalling.
