Abstract

The field of fluid-structure interaction (FSI) has important
applications ranging from the bio-medical to the civil and
aeronautical engineering fields. Despite the different approaches
developed over recent years the general solution of FSI problems
remains however far from being closed. This paper addresses the
theoretical analysis of a several partitioned solution schemes
 for FSI. This is achieved by choosing a simple but
representative model problem which allows to obtain analytical
results. A loose coupling partitioned procedure is presented
first. An iterative version of the same algorithm is presented
next together with an analysis of its convergence properties and a
brief discussion of a possible acceleration strategy. Finally a
new iterative strategy based on solving a modified equation
 is described. Some examples of application of the
partitioned algorithms considered are presented including the
aeroelastic analysis of a bridge.
