On the Geometrically Nonlinear Analysis of Composite Axisymmetric Shells
Composite axisymmetric shells have numerous applications; many researchers have taken advantage of the general shell element or the semi-analytical formulation to analyze these structures. The present study is devoted to the nonlinear analysis of composite axisymmetric shells by using a 1D three nodded axisymmetric shell element. Both low and higher-order shear deformations are included in the ...
متن کاملCoupled Flap-Lag-Torsional Vibration Analysis of Pre-twisted Non-uniform Helicopter Blades
An approximate numerical mthod is presented for analysis and determination of modal characteristics in straight, pretwisted non-unifom helicopter blades. The analysis considers the coupled flapwise bending (out of plane), chordwise bending (in plane), and torsion vibration of both rotating and non-rotating blades. The proposed method is based on the integral expansion of Green functions (struct...

متن کاملCoupled CFD/CSD Analysis of a Hovering Rotor Using High Fidelity Unsteady Aerodynamics and a Geometrically Exact Rotor Blade Analysis
Abstract: This paper presents a combination of a computational structural dynamics (CSD) and high fidelity unsteady computational fluid dynamics (CFD) analysis. Regarding a helicopter in hover, aerodynamic loads are computed from the three-dimensional Navier-Stokes solver in overlapped grids, and blade motions are obtained from the geometrically exact rotor beam analysis. To couple those analys...
