摘要：We present a general formulation for the simulation of fluid flows in interation with hypoelastic
materials using the particle finite element method (PFEM). The fluid is fully coupled with the
structures which can undergo large structural displacements, rotations and deformations. The key feature
of the PFEM is the use of an updated Lagrangian description to model the motion of nodes (particles)
in both the fluid and the structure domains. A mesh connects the nodes defining the discretized domains
where the governing equations, expresed in an integral form, are solved as in the standard FEM. The
implemented code is used to solve a number of fluid-structure interaction problems including free-fluidsurfaces
and breaking waves impacting over hypoelastic structures.
