An unfitted Nitsche method for incompressible fluid–structure interaction using overlapping meshes [PDF]
Computer Methods in Applied Mechanics and Engineering, 2014 We consider the extension of the Nitsche method to the case of fluid–structure interaction problems on unfitted meshes. We give a stability analysis for the space semi-discretized problem and show how this estimate may be used to derive optimal error ...

On the fluid-structure interaction in the cochlea
The Journal of the Acoustical Society of America, 2014The cochlea is known to be a nonlinear system that shows strong fluid-structure coupling. In this work, the monolithic state space approach to cochlear modeling [Rapson et al., J. Acoust. Soc. Am. 131, 3925–3952 (2012)] is used to study the inherent nature of this coupling.

Modeling Fluid-Structure Interaction
Journal of Guidance, Control, and Dynamics, 1997Summary: A methodology for modeling the dynamics of a structure interacting with a fluid having a free surface is addressed. In this context, a structure is either a single-rigid container or a rigid container coupled to a flexible multibody system. All nonlinearities inherent in the dynamics of the structure are taken into account.

Fluid-Structure Interaction of Propellers
2008The performance of a propeller is influenced by the wake of the ship, which results in an unsteady inflow to the propeller. Thus, the pressure on the propeller and its distribution as well as the resulting torque and thrust fluctuate during a revolution. These variations may evoke vibration of the propulsion system and a further transfer of the induced

Fluid-structure interaction and ADINA
Computers & Structures, 1983Abstract The theoretical basis of a fluid-structure interaction decoupling approximation for transient analysis of wave excited submerged structures is outlined. The approximation, called the Doubly Asymptotic Approximation (DAA) has been included in ADINA. Program modifications and additions are described.

Structures in contact with fluid flow, whether natural or man-made, are inevitably subject to flow-induced forces and flow-induced vibration: from plant leaves to traffic signs and to more substantial structures, such as bridge decks and heat exchanger tubes.

Fluid-structure interaction (FSI) is the interaction of some movable or deformable structure with an internal or surrounding fluid flow. FSI is an interdisciplinary research field with several applications in structural engineering, e.g., interaction of reservoir water, dam, and the surrounding canyon, or dynamic interaction of wind with high-rise ...

This article reviews finite element methods that are widely used in the analysis of solids and structures, and they provide great benefits in product design. In fact, with today’s highly competitive design and manufacturing markets, it is nearly impossible to ignore the advances that have been made in the computer analysis of structures without losing ...
