In this work a Lagrangian finite element approach is developed for the solution of fluid-structure interaction problems. The fluid subproblem is solved with the Particle Finite Element Method, while the structural subproblem with a classical finite element approach.

Abstract
In this work a Lagrangian finite element approach is developed for the solution of fluid-structure interaction problems. The fluid subproblem is solved with the Particle Finite Element Method, while the structural subproblem with a classical finite element approach. Particular attention has been paid to the identification of the interaction boundaries and to the remeshing strategy, to avoid excessive concentration or rarefaction of nodes in regions of the fluid mesh.File in questo prodotto:
