Added-mass effect in the design of partitioned algorithms for fluid-structure problems
TL;DR: A simplified model representing the interaction between a potential fluid and a linear elastic thin tube is considered, which reproduces propagation phenomena and takes into account the added-mass effect of the fluid on the structure, which is known to be source of numerical difficulties.

Fluid structure interaction with large structural displacements
P. Le Tallec,Jean Mouro +1 more
TL;DR: In this article, the authors propose to decompose the problem into a fluid and a structural part through an additive decomposition of the space of kinematically admissible test functions, which can be discretised in time by implicit, stable, energy conserving time integration schemes and solved by simple, iterative uncoupled algorithms.

A new strategy for finite element computations involving moving boundaries and interfaces—the deforming-spatial-domain/space-time procedure. I: The concept and the preliminary numerical tests
TL;DR: In this paper, a new strategy based on the stabilized space-time finite element formulation is proposed for computations involving moving boundaries and interfaces, where the deformation of the spatial domain with respect to time is taken into account automatically.

Interpolation using surface splines.
TL;DR: A surface spline is a mathematical tool for interpolating a function of two variables as discussed by the authors, which is based upon the small deflection equation of an infinite plate and requires the use of a digital computer.
