Abstract: The honeycomb core of cells was modeled as a layer of orthotropic material whose physical and the mechanical properties were determined by using the corrected Gibson's formula. Based on the Reddy Third-order shear plate theory, a preliminary study was conducted for the natural frequency of the super elliptical honeycomb panels with simply supported boundary conditions. Comparing the FEM results with experimental data of concrete calculated examples, it shows the method mentioned in this article has great calculation precision. The effects of panel width, thickness and structure parameters of core layer cell on the natural frequency of super elliptical honeycomb panels with simply supported boundary conditions were investigated. And plotted corresponding graphs will guide the further research and engineering application of super elliptical honeycomb panels.
