Abstract
The resistance of metallic foam-filled sandwich plate with trapezoidal plate core under blast loading is studied. The role of metal foam filling the interstice of metal sandwich plate is investigated to ascertain the effect of foam on the structural performance. The results are compared with those of unfilled trapezoidal plate core sandwich plate having the same weight. Large deflection and resistance of metallic sandwich plate to blast loading is analytically and numerically analysed. The impulsive blast loading is applied to the sandwich plate with infinite length and fully clamped along the sides. Additionally, the normal and longitudinal compressive stresses in the foam-filled trapezoidal plate core are analytically obtained.
