Stress Analysis of a Variable Thickness Rotating FGM Disc
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 6
Abstract
A mathematical model to describe stress analysis in a functionally graded rotating disc having linearly varying thickness has been investigated. The properties of the disc material like density and young’s modulus are assumed as power functions of disc radius. The stress analysis of the FGM disc with variable thickness has been compared with a similar disc but having constant thickness. It is observed that compared to uniform thickness disc the radial and tangential stresses in the variable thickness disc decreases throughout. The strain rates in the FGM disc with variable thickness are significantly reduced over the entire radius than the constant thickness disc.
