Abstract
- The aim of this paper is to analyse the stress levels in a composite centrifugal fan impeller in a steady-state condition. In the solution procedure a cyclic symmetric approach is used, coupled with a modified Potter's scheme of solving simultaneous equations. This means less computer time and memory are required. Two composite materials, namely glass-epoxy and boron-epoxy, have been studied. Radial and circumferential fibre orientations are analysed. Maximum stress levels at different speeds have been calculated. Maximum deflections and factor of safety at 2000 rpm under both fibre orientations for the above materials are obtained.
