The aim of this work is to model the transient dynamic interaction between multicomponent compressible fluid flows and general elastoplastic structures, possibly undergoing large motions and deformations. The fluid domain is treated by a node‐centred finite volume method, using an approximate Riemann solver to compute the numerical flux. The use of an arbitrary Lagrangian–Eulerian kinematical description and a non‐structured fluid grid is essential for the adopted coupling strategy with the structural domain, which is modelled by finite elements and uses a Lagrangian description. © 1997 John Wiley & Sons, Ltd.
