It is shown that electrophoretic deposition (EPD) sintering is a technological sequence that is capable of producing net-shape bulk functionally graded materials (FGM). By controlling the shape of the deposition electrode, components of complex shapes can be obtained. To enable sintering net-shape capabilities, a novel optimization algorithm and procedure for the fabrication of net-shape functi...

In this paper, static and free vibrations behaviors of the orthotropic functionally graded material (FGM) plates resting on the two-parameter elastic foundation are analyzed by the a mesh-free method based on the first order shear deformation plate theory (FSDT). The mesh-free method is based on moving least squares (MLS) shape functions and essential boundary conditions are imposed by transfer...

Functionally Graded Materials (FGM) parts are heterogeneous objects with material composition and microstructure that change gradually into the parts. The distinctive feature of FGM structure gives the possibility of selecting the distribution of properties to achieve the desired functions. Today, multimaterial parts manufactured with additive manufacturing processes are not functional. To move...

this research develops thermo-elastic analysis of a functionally graded cylinder under thermo-mechanical loadings. heat conduction equation in cylindrical coordinate system is solved. thermal conductivity coefficient is graded along the radial direction. by considering a symmetric distribution of temperature, loading and boundary conditions, strain-displacement and stress-strain relations can b...

Materials that are functionally graded and have a layered structure made of nickel aluminum were fabricated by powder metallurgy procedure. Al/Ni FGM consist five layers. The material sample starts with pure ends nickel. the layers (25 Ni-75Al) %, (50 Ni-50 Al) % (75 Ni-25Al) %. Samples sintered at temperature 600° C. Apparent density, green porosity, shrinkage each layer measured.

In this paper, the free vibration characteristics of Sigmoid Functionally Graded Material (S-FGM) Levy-type plates are investigated by developing Dynamic Stiffness Method (DSM) through application Wittrick-Williams algorithm, as solution technique. Kirchoff-Love Plate Theory (KLPT) and Hamilton principle utilised to derive governing equation motion associated natural boundary conditions. Based ...

Tribological behavior of powder metallurgically processes AlSi-MWCNT functionally graded materials was apparatus with pins on discs examined. Using a Taguchi design experiments, the signal-to-noise ratio, analysis variance, and an orthogonal array were all used to determine best testing parameters. Analysis revealed wear loss occurs due increase in load sliding distance reduced MWCNT increased ...

Abstract. The evolution of Friction Stir Consolidation (FSC) from recycling towards upcycling technique proved to be one the excellent solid-state methods for manufacturing functionally graded billets. Multi-material Functional Graded Materials (FGMs) represent a novel class materials characterized by gradual change in properties and functions which can tailored enhance components performance. ...

In this paper, several analyses were conducted to investigate the buckling behavior of Functionally Graded Material (FGM) thin plates with various circular cutout arrangements. The computer model was simulated using Finite Element (FE) software ABAQUS. developed validated by authors in previous research. A parametric analysis employed effect plate thickness and diameter on FGM plates. normalize...
