This study analyzes the free vibration, forced vibration, resonance, and stress wave propagation of orthotropic sandwich plates made of functionally graded materials (FGMs). Dynamic analyses are conducted using a mesh-free method based on first-order shear deformation theory and the shape functions constructed using moving least squares approximation. The sandwich plates are rested on a Pastern...

Functionally graded materials have gained considerable attention in the high-temperature applications. A study of parametric vibrations of functionally graded plates subjected to in-plane time-dependent forces is presented. Moderately large deflection equations taking into account a coupling of in-plane and transverse motions are used. Material properties are graded in the thickness direction o...

An advantage of functionally graded materials (FGMs) over laminated composites is that material properties vary continuously in an FGM but are discontinuous across adjoining layers in laminated composites. Furthermore, in an FGM material, properties can be graded in all three directions which is more difficult to achieve in laminated composites. FGMs have been used for structural optimization, ...

Computer simulation and FEM analysis of the stress-strain state thin plates thin-walled cylindrical shells, weakened by a circular hole in presence an annular inclusion functionally graded material (FGM) surrounding it, have been carried out. The influence dimensions FGM-inclusion law change its elastic modulus on concentration parameters shells vicinity is studied. distribution stress strain i...

In this paper, several analyses were conducted to investigate the buckling behavior of Functionally Graded Material (FGM) thin plates with various circular cutout arrangements. The computer model was simulated using Finite Element (FE) software ABAQUS. developed validated by authors in previous research. A parametric analysis employed effect plate thickness and diameter on FGM plates. normalize...
