STRUCTURAL MODELLING OF ROTATING FUNCTIONALLY GRADED TAPERED BLADES UNDER THERMAL LOADING
 
This paper is aimed to evaluate rotating tapered blades made of Functionally Graded Material(FGM) in point of structural modelling under thermal loading. Effectiveness on system efficiency is substantial in which material features, design methods, process of engineering applications, rotating components, tapered blades in turbine or helicopters. A selection of material is so important for structural modelling. In consequence of the improvement of composite material technology, usages of FGMs have begun to increase in such engineering applications. They have a special character that their material properties are continuous along the structure; thus, stress concentrations are decreased regularly. While structural integrity of FGM is sustained, it can endure against high temperatures. This qualification makes this paper significant in respect to evaluate process on structural modelling of rotating blades under thermal loading. The blade formulations were obtained from Euler-Bernoulli Beam Theory to examine the effects of different parameters on the vibration characteristics. In the solution part, these parameters are hub rotating speed, material property, power law index parameter and rotary inertia and shear deformation. Finite Element Method(FEM) was used for developing the mathematical models. Application of the FEM in beam theory was verified by MATLAB. Finally, It is targeted that findings of this study will be demonstrated in the full paper. This study was produced from a part of the first-ranked author's unpublished thesis.
