摘要：We propose a Lagrangian framework for modelling fluid-structure interaction
(FSI) problems with free surfaces flows. The model is based on a Lagrangian
approach for describing the fluid and structural dynamics. Our approach
allows to treat the whole FSI domain as a single entity and describes its
behaviour by a single set of momentum and continuity equations and which is
solved using a single numerical method. This work uses the Particle Finite
Element Method (PFEM) to solve the resulting differential equations. The PFEM
is an effective technique for modelling complex interactions between floating
and submerged bodies and free surface flows, accounting for splashing of waves,
large motions of the bodies and frictional contact conditions. Examples are
presented based on the model including free surfaces flows and breaking waves
impacting over elastics structures.
