Characterization of Materials in Some Structural Components

Abstract

This Thesis deals with the study of characterization of materials in a disc made of newlineisotropic material and transversely isotropic material. Discs are widely used components in newlinemany applications in mechanical, chemical processing and aerospace industries such as newlineflywheels, high speed gear engines, turbo generators, compressors, sink fits, pumps, steam newlineturbine, computer discs, etc. Seth s transition theory and generalized strain measure are used newlinefor finding the governing equation. newlineMathematical modelling is based on stress strain relation and equilibrium equation. newlineAnalytical solutions are presented for the rotating disc made of transversely isotropic material newlineand isotropic material. The effects of different pertinent parameters (i.e. temperature, variable newlinedensity, mechanical load and thickness) are considered for the discs made of isotropic / newlinetransversely isotropic material. newlineThe behaviour of stress distribution, mechanical load, thickness variation, strain rates, newlineand temperature distribution are investigated. The compressibility and incompressibility newlinefactors were considered in the case of rotating disc made of isotropic material. All the problems newlinewhich are solved in this thesis have considered the non-linear character of transition. Results newlinehave been discussed numerically and graphically.
