Creep Deformation and Stress Analysis in Rotating Disc of Composite Material

Abstract

Creep is the tendency of a solid material to slowly move or deform permanently under the influence of stresses when subjected to high temperatures for long duration of time. So creep is one of the major considerations while analyzing the materials which are used for high temperature for long durations. Discs are used under high temperatures mainly in turbines, aeroengines,automobiles, pumps and compressors. So creep analysis of composite material disc has a wide scope for research. In this research work the radial and circumferential stress analysis of the disc when subjected to Angular Velocity at high temperatures for long durations of time is done with the help of Ansys Software. The validation of the results is proved by matching the results with Hamid Jahed et al. [4].. From the results obtained it is clear that they are in accordance with the results obtained by Hamid Jahed et al. [4]. In the study when we increase angular velocity the radial stress firstly increase and then decreases but circumferential stress decrease by increase in angular velocity. There for we can say that in a rotating disc the most stressed area near to the center.
