On the Development of Refined Plate Theory for Static Bending Behavior of Functionally Graded Plates

Abstract EN

This work gives information about the development of refined plate theory to study the static bending behavior of functionally graded material (FGM) plates.

The significant advantage of our proposed theory is that only one unknown variable exists in its displacement formula and governing equation.

To illustrate the accuracy and effectiveness of this theory, an analytical approach based on the Navier solution is employed to obtain the solution for static bending of simply supported FGM plates.

A good agreement for static bending of FGM plates with other literature results has been instituted.

This work also investigates the deflection, in-plane normal, and shear stresses of sinusoidally loaded FGM rectangular plates with four simply supported edges.

The influence of some parameters on the bending performance of FGM plates is also carefully considered.
