Resumen:
We present a general Lagrangian formulation for treating elastic solidsand quasi/fully incompressible fluids in a unified form. The formulation allows totreat solid and fluid subdomains in a unified manner in fluid-structure interaction(FSI) situations. In our work the FSI problem is solved via the Particle FiniteElement Method (PFEM). The PFEM is an effective technique for modeling com-plex interactions between floating and submerged bodies and free surface flows,accounting for splashing of waves, large motions of the bodies and frictional contactconditions. Applications of the unified Lagrangian formulation to a number of FSIproblems are given.
