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...

Laser powder bed fusion (LPBF) of multi-material and functionally graded materials (FGM) has attracted significant research interest due to its ability fabricate components with superior performance compared those manufactured single material. However, the forming mechanisms various defects remain unknown. In this paper, a DEM-CFD model was first established obtain an in-depth understanding pro...

Abstract In this study we present a numerical approach to solve steady-state heat conduction problems in functionally graded materials (FGMs). Two different types of material gradations are considered for spatially varying thermal conductivity FGM: (1) Quadratic gradation; (2) Exponential gradation. The proposed procedure is based on finite-difference method and developed the equation over gene...

Hydroxyapatite (HA) and bioglass (BG) ceramics have become of prime importance in bone tissue engineering. Besides the appropriate composition, microstructure replacement plays a crucial role. In present work, particle composites functionally graded material (FGM) based on HA BG prepared by electrophoretic deposition were thoroughly characterised terms preparation method, sintering process, pha...

Functionally graded material (FGM) arches may be subjected to a locally radial load and have different distributions leading nonlinear in-plane buckling behavior. Little studies is presented about effects of the type on FGM under in literature insofar. This paper focuses investigating behavior fixed uniformly distributed incorporating distributions. New theoretical solutions for limit point bif...
