Computer Aided Thermal Stress Analysis of Orthotopic Rotating Disc

Nayak, Jitendra (2009) Computer Aided Thermal Stress Analysis of Orthotopic Rotating Disc. BTech thesis.



This study deals with stress analysis on orthotropic rotating annular discs subjected to various temperature distributions, such as uniform, linearly increasing and decreasing with radius temperatures. Tangential and radial stresses in a rotating disc under the three different temperature profiles are plotted in figures. With the increasing temperature, the tangential stress component decreases at the inner surface whereas it increases at the outer surface, and the radial stress component reduces gradually for all the temperature distributions. The magnitude of the tangential stress component is higher than that of the radial stress component for all the discs under the lower temperatures of the temperature distributions. But, when the temperature is further increased, the tangential stress component decreases more at the inner surface. The radial displacement is also calculated analytically and has higher value at the outer surface than that of the inner surface for all the temperature distributions, except for radial displacement in the reference temperature.
