What is it about?

This work studies the dispersion relations of wave propagation in infinite advanced (FGM) plates. The influences of gradation power, porosity and the viscoelastic foundation's parameters on wave propagation in an FG plate are examined and discussed .

Why is it important?

This article deals with the wave propagation characteristics of infinite FG ceramic-metal plates with porosity resting on a viscoelastic foundation. A simple four-variable integral hyperbolic shear deformation plate theory is proposed for the solution. This theory implies two undetermined integral terms with a hyperbolic shape function in the displacement field to describe the shear rotations in both the xz-plane and the yz-plane with a single unknown while satisfying the boundary conditions in both faces of the plate without the need for shear correction coefficients.
