Abstract

This paper is devoted to the thermoelastic modeling and dynamic response of pretwisted rotating blades made of functionally graded ceramic-metal based materials. The blade is modeled as a non-uniform thin walled beams fixed at the hub at a setting angle. The blade is rotating with a constant angular velocity and is exposed to a steady temperature field as well as external excitation. Moreover, the effect of the temperature field and is impacted by a pressure pulse. The material properties are graded in the blade thickness direction according to a simple power law distribution. The numerical results highlight 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, which are provided for the case of a biconvex cross section, and pertinent conclusions are outlined.
