Higher-Order Free Vibration Analysis of Porous Functionally Graded Plates

The present work analyzes the free vibration response of functionally graded (FG) plates made of Aluminum (Al) and Alumina (Al<sub>2</sub>O<sub>3</sub>) with different porosity distributions, as usually induced by a manufacturing process. The problem is tackled theoretically...

The problem is tackled theoretically based on a higher-order shear deformation plate theory, while proposing a Navier-type approximation to solve the governing equations for simply-supported plates with different porosity distributions in the thickness direction.
