Creep and Rupture Time response in a transversely isotropic rotating disc

Sujata Goyal, Manish Garg

Abstract

The steady states creep and rupture time response in a transversely isotropic FG rotating disc has been investigated. The disc under investigation is made of FGM containing non-linear distribution of silicon carbide particle (SiCp) in a matrix of pure aluminum along the radial distance. The stresses and strain rates in the FGM disc have been estimated for different values of anisotropic constant varying between 0.5 to 1.5. It is observed that radial stress in the disc decreases a little by increasing from 0.5 to 1.5. However, the tangential stress in the disc increases near the inner radius, but decreases towards the outer radius when increases from 0.5 to 1.5. The radial as well as tangential strain rates in the FGM disc are significantly reduce with the increase in extent of anisotropy from 0.5 to 1.5.
