FGM ROTATING DISC FABRICATE BY Al/Al2O3
Our aim of is to develop a processing method for a rotating disc made of functionally graded materials (FGM), by stacking the slurry, layer by layer in a radial direction. A three-layer functionally graded material of Al/Al2O3 is fabricated with compositions of 10, 20, 30 vol.% Al2O3. The ceramic composition increases from the discs inner (centre) to the outer. The combination of these material...
متن کاملCreep Analysis of an Isotropic Functionally Graded Rotating Disc
Abstract Creep response for isotropic axisymmetric rotating disc made of a particle-reinforced FGM has been investigated in the present study. The result obtained for non linear variation of particle distribution along the radial distance of the disc are compared with that of discs containing the same amount of particle distributed uniformly or linearly along the radial distance. The disc under...
متن کاملCreep Modeling in a Composite Rotating Disc with Thickness Variation in Presence of Residual Stress
Steady-state creep response in a rotating disc made of Al-SiC particle composite having linearly varying thickness has been carried out using isotropic/anisotropic Hoffman yield criterion and results are comparedwith those using vonMises yield criterion/Hill’s criterion ignoring difference in yield stresses. The steady-state creep behavior has been described by Sherby’s creep law. The material ...
متن کاملEdge Crack Studies in Rotating FGM Disks
This article focused on the stress analysis of an edge crack in a thin hallow rotating functionally graded material (FGM) disk. The disk is assumed to be isotropic with exponentially varying elastic modulus in the radial direction. A comprehensive study is carried out for various combinations of the crack length and orientation with the different gradation of materials. The effect of non-unifor...
متن کاملCreep Transition in a Thin Rotating Disc Having Variable Density with Inclusion
Creep stresses and strain rates have been obtained for a thin rotating disc having variable density with inclusion by using Seth’s transition theory. The density of the disc is assumed to vary radially, i.e. ( ) 0 / m r b ρ ρ − = ; 0 ρ and m being real positive constants. It has been observed that a disc, whose density increases radially, rotates at higher angular speed, thus decreasing the pos...
