SOME RECENT ADVANCES IN NONLINEAR AEROELASTICITY: FLUID-STRUCTURE INTERACTION IN THE 21 CENTURY ABSTRACT Aeroelasticity is the field that examines, models and seeks to understand the interaction of the force from an aerodynamic flow and the deformation of an elastic structure. The forces produce deformation, but the structural deformation in turn changes the aerodynamic forces. This feedback between force and deformation leads to a variety of dynamic responses of the fluid and the structure including flutter (a Hopf bifurcation instability), limit cycle oscillations and sometimes chaos. Selected recent advances in nonlinear aeroelasticity and fluid-structural interaction are reviewed to identify and model the fundamental elements that they share. Topics to be discussed will be chosen from among the following.

Seismic Evaluation of Flexible-Base Low-Rise Steel Frames Using Beam-On-Nonlinear-Winkler-Foundation Modeling of Shallow Footings
Recent investigations have shown that the influences of Soil-Structure Interaction (SSI) may be detrimental to the seismic response of structure, and hence neglecting this phenomenon in analysis and design may lead to an un-conservative design. The objective of this paper is to quantify the effects of nonlinear soil-structure interaction on the seismic response of a low-rise special moment fram...

Fluid-structure interaction (FSI) occurs when the dynamic water hammer forces; cause vibrations in the pipe wall. FSI in pipe systems due to Poisson and junction coupling has been the center of attention in recent years. It causes fluctuations in pressure heads and vibrations in the pipe wall. The governing equations of this phenomenon include a system of first order hyperbolic partial differen...

Nonlinear vibration of a fluid-filled single walled carbon nanotube (SWCNT) with simply supported ends is investigated in this paper based on Von-Karman’s geometric nonlinearity and the simplified Donnell’s shell theory. The effects of the small scales are considered by using the nonlocal theory and the Galerkin's procedure is used to discretize partial differential equations of the governing i...
