✦ Synopsis

The aim of this work is to model the transient dynamic interaction between multicomponent compressible ¯uid ¯ows and general elastoplastic structures, possibly undergoing large motions and deformations. The ¯uid domain is treated by a node-centred ®nite volume method, using an approximate Riemann solver to compute the numerical ¯ux. The use of an arbitrary Lagrangian±Eulerian kinematical description and a non-structured ¯uid grid is essential for the adopted coupling strategy with the structural domain, which is modelled by ®nite elements and uses a Lagrangian description.

The objective of the paper is to present an implicit algorithm for incompressible fluid flow solution using the arbitrary Lagrangian-Eulerian (ALE) formulation and to investigate solution accuracy and stability of the algorithm. The governing equations of the implicit procedure are derived using iso
