In this study, torsional wave propagation is investigated in a rod that are made of one and two dimensional functionally graded material. Firstly, the governing equations of the wave propagation in the functionally graded cylinder derived in polar coordinate. Secondly, finite difference method is used to discretize the equations. The Von Neumann stability approach is used to obtain the time ste...

Recent developments in medical and dental fields have warranted biomedical objects or implants with desirable properties for biomedical applications. For example, artificial hip joints, tissue scaffolds, and bone and jaw structures are now commonly used in hospitals to assist complex surgical operations, and as specimens for experiments in pharmaceutical manufacturing enterprises. But most biom...

Abstract The present research focuses on two-dimensional deformation in a functionally graded thermoelastic micro-elongated medium. It is supposed that the non-homogeneous properties (thermal and mechanical) of FGM are x-direction. normal mode technique used to acquire analytic expression for displacement components, stress, micro-elongation temperature. cause effect relationship non-homogeneit...

High-speed aerospace applications, such as re-entry vehicles, mostly involve thin-walled structural components with a high strength-to-weight ratio and high-temperature resistant. The present novel work comprises the thermal analysis of vehicle nose structures made four functionally graded materials (FGM). Four FGM shell aluminum/silicon carbide, aluminum/aluminum oxide, Ti-6Al-4V/silicon carbi...

An analysis out to study effect size and geometry openings in FGM plate on critical load. circular, square, diamond vary based ratio opening diameter width plate. Moreover, aspect ...

Transient wave processes in viscoelastic structures built from functionally graded material (FGM) still remain almost unexplored. In this article, the problem of propagation nonstationary longitudinal waves an infinite layer a FGM with plane–parallel boundaries is considered. The physical and mechanical parameters depend continuously on transverse coordinate, while process propagates along same...

in the present paper, an exact solution for transient response of an infinitely long functionally graded thick-walled cylinder subjected to dynamic pressures at the boundary surfaces is presented for arbitrary initial conditions. the cylinder is assumed to have a plane-strain condition and the dynamic pressures are assumed to be imposed uniformly and axisymmetrically on the boundary surfaces. m...

In this article, vibration characteristics and the parametric instability of functionally graded material (FGM) plates with cyclic loading in a hygrothermal field are discussed. The plate element is modeled in a finite element by applying the third-order shear deformation hypothesis. The mathematical formulation of the FGM plate is made with two material constituents by applying the power rule ...

In this work, a finite element model to perform the thermal–structural analysis of beams made functionally graded material (FGM) is presented. The formulation based on third-order shear deformation theory. constituents FGM are considered vary only in thickness direction, and effective properties evaluated by means rule mixtures. volume distribution top constituent modeled using power law form. ...
