Functionally graded materials (FGMs) are the advanced materials with varing properties in dimensions. These are made of two or more constituent phases with continuous and smoothly varying composition in preferred directions. The properties of material depend on the spatial position in the structure of material. These materials are gaining attention for biomedical application as biomaterials owi...

In this research, mechanical buckling of rectangular plates of functionally graded materials (FGMs) is considered. Equilibrium and stability equations of a FGM rectangular plate under uniform in-plane compression are derived. For isotropic materials, convergent buckling loads have been presented for non-uniformly compressed rectangular plates based on a rigorous superposition fourier solution f...

Al/SiC functionally graded and metal-matrix composites were investigated through dynamic mechanical analyzer as a function of vibrating frequencies. It was found that internal frictions strongly dependent on material type frequency. Tan ? reached 30.4 × 10–3 21.2 10–3in FGM MMC, respectively, at frequency 1 Hz. The damping capacity decreased the increased to 10 Hz 30 Storage moduli 172 GPa 144 ...

Functionally graded materials (FGM) present enormous potential to combine with distinct mechanical and thermal properties in a component via compositional gradient throughout the body. In work, step Al2O3/NbC composites were assessed order obtain FGM high hardness good fracture toughness. Step uniaxially pressed cylinders consolidated by Spark plasma sintering (SPS) into fully dense (>99% TD) c...

Abstract In this study, a coupling model of fluid-conveying pipes made functionally graded materials (FGMs) with NiTiNOL-steel (NiTi-ST) for vibration absorption is investigated. The responses the FGM pipe NiTi-ST are studied by Galerkin truncation method (GTM) and harmonic balance (HBM). solutions numerical results consistent. Also, linearized stability structure determined. effects parameters...

This paper analyses free vibrations of framed nanostructures made Functionally Graded Material (FGM) based on the Nonlocal Elastic Theory (NET) and Dynamic Stiffness Method (DSM). FGM characteristics vary nonlinearly throughout height beam element. The NET considers nonlocal parameter that perfectly captured size effect nanostructures. However, makes paradoxes in bending vibration behaviour wit...

The present study deals with the elastic analysis of concave thickness rotating disks made of functionally graded materials (FGMs).The analysis is carried out using element based gradation of material properties in radial direction over the discretized domain. The resulting deformation and stresses are evaluated for free-free boundary condition and the effect of grading index on the deformation...
