Resistance of metallic foam-filled trapezoidal plate core sandwich plate to blast loading

摘要

The resistance of metallic foam-filled sandwich plate with trapezoidal plate core under blastnloading is studied. The role of metal foam filling the interstice of metal sandwich plate isninvestigated to ascertain the effect of foam on the structural performance. The results arencompared with those of unfilled trapezoidal plate core sandwich plate having the same weight.nLarge deflection and resistance of metallic sandwich plate to blast loading is analytically andnnumerically analysed. The impulsive blast loading is applied to the sandwich plate with infinitenlength and fully clamped along the sides. Additionally, the normal and longitudinal compressivenstresses in the foam-filled trapezoidal plate core are analytically obtained.
