Abstract

Abstract
The present study reports stress and deformation analysis of rotating thick truncated conical shells made of exponentially varying functionally graded material, subjected to linearly varying internal pressure. Material properties of the shells are graded exponentially along the axial direction. Metal-ceramic as well as ceramic-metal (FGM) of aluminum metal and zirconia ceramic is considered. The stresses and deformation behavior are evaluated at different surfaces along the radius and at different angular velocities. A comparison of behavior of FGM shells and homogeneous shell is also made. Numerical results obtained shows that the stresses and deformation are maximum at inner surface, near the bottom zone and it is observed that the effect of angular velocity is more dominant over internal pressure, at high speeds.
