Dynamic and aeroelastic action of guy cables
The models have been derived for the computation of the dynamic stiffness of guy cables. Both the complete mathematical model and the simplified spring-mass model can be used in a linear three-dimensional dynamic analysis of guyed masts in connection with the frequency response method and a substructure technique where frequency dependent springs a...
Farey sequences of spatiotemporal patterns in video feedback
In this paper we present an experimental and theoretical description of the dynamic of spatial patterns obtained in a video feedback loop. A video camera monitors the screen to which it is connected and can turn around its optical axis at an angle ␣. Under certain conditions of brightness and magnification, this optoelectronic system produces spati...

A method for identification of non-linear multi-degree-of-freedom systems
peer reviewed / System identification methods for non-linear aeroelastic systems could find uses in many aeroelastic applications such as validating finite element models and tracking the stability of aircraft during flight flutter testing. The effectiveness of existing non-linear system identification techniques is limited by various factors such ...

Numerical Continuation Applied to Panel Flutter
Published in Nonlinear Dynamics
The panel flutter formulation studied here includes a geometricnonlinearity. In a physical sense, the nonlinearity represents couplingbetween out-of-plane bending and in-plane stretching. To investigate theinitial condition response, the pseudo-arclength continuation method isapplied to this problem. The continuation method is an alternatenumerical...
Platform for Multi-Model Design
Published in Flow, Turbulence and Combustion
This paper introduces a global platform for the simulation and the design of multi-model configurations. Fluid-structure interaction and optimization procedures are coupled with turbulent incompressible and compressible flow solvers in order to treat complex aerodynamics problems. First, the equations used in modeling the fluid and the structure ar...
Non-Linear Unsteady Aerodynamic Response Approximation Using Multi-Layer Functionals
Non-linear functional representation of the aerodynamic response provides a convenient mathematical model for motion-induced unsteady transonic aerodynamic loads response, that accounts for both complex non-linearities and time-history effects. A recent development, based on functional approximation theory, has established a novel functional form; ...
