A torsional stress analysis of hollow fans blades by the finite element method is presented. The fans are considered to be double circular arc blades, hollowed 30 percent, and twisted by a component of the centrifugal force by the rated revolution. The effects of blade hollowing on strength and rigidity are discussed. The effects of reinforcing webs, placed in the hollowed section in varying numbers and locations, on torsional rigidity and the convergence of stresses, are reported. A forecast of the 30 percent hollowing against torsional loadings is discussed. Ogawa, A. and Sofue, Y. and Isobe, T. Unspecified Center NASA-TM-75718, NAL-TR-533 NASW-3199

A superparametric parabolic shell element specially adapted for dynamic conditions is utilized to anlayze the vibration characteristics and dynamic stresses in a hollow aerofoil and symmetrical shell type turbine blades. The efficiency of the element developed is investigated and is shown to be superior to other available elements. Various results are presented to establish the dependence of the frequency on the geometric parameters. Relative principal stress distributions on a hollow turbine blade, for various modes of vibration, are presented indicating the variation of the point of maximum dynamic stresses with mode order. These points are the critical points where the fatigue cracks may originate leading to the final destruction. (Author).

This book concerns the development of novel finite elements for the structural analysis of composite beams and blades. The introduction of material damping is also an important aspect of composite structures and it is presented here in terms of their static and dynamic behavior. The book thoroughly presents a new shear beam finite element, which entails new blade section mechanics, capable of predicting structural blade coupling due to composite coupling and/or internal section geometry. Theoretical background is further expanded towards the inclusion of nonlinear structural blade models and damping mechanics for composite structures. The models effectively include geometrically nonlinear terms due to large displacements and rotations, improve the modeling accuracy of very large flexible blades, and enable the modeling of rotational stiffening and buckling, as well as, nonlinear structural coupling. Validation simulations on specimen level study the geometric nonlinearities effect on the modal frequencies and damping values of composite strips of various angle-ply laminations under either tensile or buckling loading. A series of correlation cases between numerical predictions and experimental measurements give credence to the developed nonlinear beam finite element models and underline the essential role of new nonlinear damping and stiffness terms.
