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.
