Functionally graded aluminium/zirconia metal matrix composite was fabricated using stir casting technique followed by horizontal centrifugal casting process and a hollow cylindrical functionally graded composite (150 x 150 x 16 mm) was obtained with centrifuging speed of 1200 rpm. The microstructural evaluation and hardness test was carried out on the outer and inner surface of the functionally...

In this work, functionally graded materials were synthesized by centrifugal technique at different volume fractions 0.5, 1, 1.5, and 2% Vf with a rotation speed of 1200 rpm constant time, T = 6 min . The mechanical properties characterized to study the non-graded nanocomposites pure epoxy material. tests showed that added alumina (Al2O3) nanoparticles enhanced effect more than epoxy. maximum di...

The Steady state creep behaviour of a functionally graded cylinder made of isotropic composite containing varying distribution of silicon carbide particles has been investigated by a mathematical model. The creep behaviour of the FGM is described by a Norton's Power law. The effect of varying distribution of SiCP particles of creep stresses and creep rates in the FGM cylinder has been anal...

Abstract This article investigates the novel mechanical behavior of metal–metal gradients (Al/Zn) functionally graded materials (FGM) type. The experimental work includes manufacture three different models (FGM 1, FGM 2, and 3) with various proportions volume fraction gradation as (100% Al–50% Zn–50% Al–100% Zn), Al–30% Zn–70% Al–70% Zn–30% Zn) respectively. annealing process was carried out to...

Image processing, power engineering, robotics, industrial automation etc., have all found successful uses for artificial intelligence (AI) techniques such as neural networks (ANN) and neuro-fuzzy logic (FL). In this study, an adaptive inference system (ANFIS) modelling of machine learning (ML) has been implemented to estimate the tribological properties functionally graded materials (FGM). Thes...

abstract: a time domain semi-analytical solution to study thermoelastic creep behavior of  functionally graded rotating axisymmetric disks with variable thickness is presented. the rate type governing differential equations for the considered structure are derived and analytically solved. to solve these  equations, the disk is divided into some virtual sub-domains. general solution of  equilibr...

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, ...

The need for functionally graded material (FGM) parts has surfaced with the development of material science and additive manufacturing techniques. Direct Metal Deposition (DMD) processes can locally deposit different metallic powders to produce FGM parts. Yet inappropriate mixing of materials without considering the influence of varying dilution rates and the variation of material properties ca...
