Study of thermal gradation on creep deformation of non-linear varying functionally graded rotating disc.

Abstract

Rotating discs working at high temperature finds its application in many dynamic devices like turbo generators, turbojet engines, gas and steam turbine rotors, centrifugal compressors and components like flywheels, gears, etc. and in many such industrial applications. Thus, in the present work, mathematical modeling have been done to investigate the effect of parabolic temperature distribution on secondary stage deformation in non-linear functionally graded composite disc along both radial and tangential directions. Sherby’s law helps to calculate creep behavior of composite rotating disc. MATLAB software is used to model stress and strain rate distributions occurring in composite disc working at different temperature profiles.
