Özet

This study deals with the thermal stress analysis of a curvilinearly orthotropic rotating annular disc under internal and external pressures. The temperature distribution is chosen to vary parabolically from the inner surface to the outer surface along the radial section. With an increasing temperature, the tangential stress component decreases at the inner surface whereas it increases at the outer surface, and the radial stress component goes down gradually. The magnitude of the tangential stress component is higher than that of the radial stress component. The radial displacement is calculated analytically and has higher values at the inner surface than that of the outer surface, for all the temperature distributions. The stresses and the radial displacement obtained are also compared with the stresses and displacement in a rectilinearly hollow rotating disc of [Callioglu, H., Stress Analysis of an Orthotropic Rotating Disc under Thermal Loading, J. Reinforced Plastics and Composites, (in press)].
