Natural fibers are promising for engineering applications due to their low cost. They are abundantly available in tropical and subtropical regions of the world, and they can be employed as construction materials. Among natural fibers, bamboo has been widely used for housing construction around the world. Bamboo is an optimized composite material which exploits the concept of Functionally Graded...

in this paper, finite element elastic contact analysis of a functionally graded (fg) hollow brake disk in contact with pad, subjected to rotation, contact pressure and frictional heat is presented. the material properties vary through the thickness according to a power-law characterised by a grading index, n. the material property is purely steel at the core part and gradually moves and approac...

The aim of this paper is to determine the critical buckling load for simply supported thin shallow spherical shells made of functionally graded material (FGM) subjected to uniform external pressure. A metal-ceramic functionally graded (FG) shell with a power law distribution for volume fraction is considered, where its properties vary gradually through the shell thickness direction from pure me...

Conventional metallic foam processing seeks to maximize uniformity in pore size, relative density, and other aspects of foam structure in order to minimize property variation associated with the statistical nature of foams, and thereby increase their reliability in service. However, property uniformity is in many cases an inefficient approach to meeting overall design criteria, as demonstrated ...

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...

In this paper, the nonlinear vibration analysis of a thin cylindrical shell made of Functionally Graded Material (FGM) resting on a nonlinear viscoelastic foundation under compressive axial and lateral loads is studied. Nonlinear governing coupled partial differential equations of motions (PDEs) for cylindrical shell are derived using improved Donnell shell theory. The equations of motions (EOM...

The effects of advanced nonlinear varied shear coefficient and third-order deformation theory (TSDT) on the dynamic responses thick functionally graded material (FGM) plates under thermal vibration are investigated. displacement field TSDT is used to obtain expression for FGM plates. displacements, rotations stresses in numerical results sinusoidal applied heat loads obtained Two parametric env...

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 ...

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.
