Optimum design of metallic corrugated core sandwich panels subjected to blast loads

Global bending response of composite sandwich plates with corrugated core: Part I: Effect of geometric parameters

“…Other applications of such sandwich structures can be found in aircraft, naval, building construction and surface transportation industries. Several research studies have been published in recent years on the analysis of metallic corrugated-core sandwich panels for strength, vibration control, noise control and blast resistance [2]- [6]. When made of composite materials, corrugated-core sandwich panels can be even more attractive for structural applications because they offer a wide range of design solutions in addition to weight savings.…”

Experimental and numerical studies on the quasi-static and dynamic crushing responses of multi-layer trapezoidal aluminum corrugated sandwiches

“…There have been apparently numerous experimental and numerical investigations and reviews in the literature on the quasi-static/dynamic mechanical and impact/blast loading responses of sandwich structures with periodic cellular metal cores, including honeycomb, corrugated and lattice truss topologies, for example see the review by Wadley in 2006 [17]. The most widely investigated topologies include V-type [18,19], U-type [20,21], X-type (diamond) [22] and Y-type [19,23,24] corrugated and pyramidal truss [16,25,26] structures. The previous experimental and accompanying numerical investigations were on the single layer corrugations; while, the effect of layering on the overall performance of multi-layer corrugated metal core sandwiches has not been investigated.…”

The impact responses and the finite element modeling of layered trapezoidal corrugated aluminum core and aluminum sheet interlayer sandwich structures

“…The corrugation leads to highly directional mechanical properties and provides high stiffness in certain applications [1]. The metallic corrugated core sandwich structures of light weight and relatively high crushing loads have the potentials to be used in the applications involving impact/blast load mitigation.…”

“…There have been apparently numerous experimental and numerical investigations and reviews in the literature on the quasi-static/dynamic mechanical and impact/blast loading responses of the sandwich structures with periodic cellular metal cores, including honeycomb, corrugated and lattice truss topologies, for example see the review by Wadley in 2006 [2]. Liang et al [1] investigated the optimum weight designs of metallic corrugated core structures in transverse and axial directions. The most effective parameters on the face sheet axial stress were shown to be corrugation length and face sheet thickness, while all geometrical parameters equally affected the core axial stress.…”
