Abstract

This paper focus on the thermoelastic modeling and dynamic response of a rotating blade made of functionally graded ceramic-metal based materials. The blade is modeled as non-uniform thin walled beams which are fixed at the hub with various selected values of setting angles and pre-twisted angles. In this study, the blade rotates with a constant angular velocity and is exposed to a steady temperature field and external excitation. The effect of the temperature gradient through the blade thickness is also considered. Material properties are graded across the blade's thickness according to the volume fraction power law distribution. Numerical results highlighting the effects of the volume fraction, temperature gradient, taper ratio, setting angle and pre-twisted angle on the dynamic response of bending-bending coupled beam characteristics are provided for the case of a biconvex cross-section and pertinent conclusions are outlined.
