Free Vibration Analysis of Sandwich Beams with Functionally-Graded-Cores by Complementary Functions Method

What is it about?

The plane vibration study of a sandwich thermal protection system insulation panel with a functionally-graded core is conducted using Complementary Functions Method. The panel is assumed to be under plane-stress conditions and subjected to simply supported boundary conditions. The two-dimensional elasticity formulations are used to derive the equations of motion for each layer. The effects of the in-plane normal stresses as well as the shear stress are taken into consideration for all layers.
