Functionally graded materials

In this study, the deflection and stress field of perfect and imperfect (with and without porosities) functionally graded (FG) cylindrical panels are determined following the first-order shear deformation theory (FSDT). The panel rested on the twoparameter elastic foundation (Pasternak foundation) under pressure loads and worked in a hygro-thermal environment.

This paper presents an analytical and a numerical thermomechanical investigation of a thick-walled cylinder made of the functionally graded materials (FGMs). The hollow cylinder is subjected to a pressure and a thermal load and the properties of this material are varying across the thickness from the inner face that is a ceramic to the outer one which is a metal.

Finite element method is used to study the free vibration analysis of functionally graded skew plates. The material properties of the skew plates are assumed to vary continuously through their thickness according to a power-law distribution of the volume fractions of the plate constituents.

This thesis aims to develop finite element models for studying vibration of the 2D-FGM beam. These models require high reliability, good convergence speed and be able to evaluate the influence of material parameters, geometric parameters as well as being able to simulate the effect of shear deformation on vibration characteristics and dynamic responses of the 2D-FGM beam.
