Dynamic Response Analysis of Square Honeycomb Sandwich Plates Subjected to Blast Loading

Abstract:

The dynamic response of the square honeycomb sandwich plates subjected to blast loading was simulated and analyzed by using the finite element software ABAQUS.With the given mass per unit area,core sheet spacing and height,the optimal relative density of the core was obtained under blast loading of three levels.With this optimal relative density,the sandwich plates have the best shock resistance ability and the top and bottom face sheets have the smallest deflection subjected to impulsive load.The sandwich plates were compared with the solid plates having the same mass per unit area.The results show that the sandwich plates have higher strength and energy absorption capability.Furthermore,influence of geometrical parameters including core sheet spacing,thickness,height and face sheet thickness on the face sheetss maximum deflection were discussed.
