Finite-element free vibration and buckling analyses of sandwich plates with honeycomb and foam cores

Abstract

The free vibration and linear buckling analyses of the sandwich flat panels has been considered. The commercial finite element ABAQUS software was used to calculate natural frequencies and bearing capacities of sandwich plates with honeycomb and foam cores. These problems were analysed to assess the role of the core on the natural frequencies and critical loads of sandwich plates. The calculated for sandwich plates results were compared with those for solid plates having the same weight. According to the comparative results the structural performance of the sandwich plates are discussed.
