Abstract: |
Based on the classical model of sandwich panels,the motion governing differential equations of the square-honeycomb sandwich plates considering the discrete characteristics of the core are derived in the paper.A simple approach to reduce the governing equations for orthotropic honeycomb sandwich plates to a single equation containing only one displacement function was presented and the exact solution of the natural frequencies for rectangular honeycomb sandwich plates with all edges simply supported was obtained.The conclusions are instructive to applications of honeycomb panels in engineering. |
