TY - JOUR A1 - Wasmer, Paul A1 - Krome, Fabian A1 - Bulling, Jannis A1 - Prager, Jens T1 - A fluid model for the simulation of fluid‐structure interaction in the Scaled Boundary Finite Element Method for prismatic structures T2 - Proceedings in applied mathematics and mechanics : PAMM N2 - The Scaled Boundary Finite Element Method is known as an efficient method for the simulation of ultrasonic wave propagation. As to investigate acoustic wave behavior in case of fluid‐structure interaction, a fluid model is implemented in the SBFEM for prismatic structures. To omit coupling terms a displacement‐based formulation is used. Spurious modes, which occur in the solution, are suppressed using a penalty parameter. To verify this formulation dispersion curves obtained with Comsol Multiphysics are compared to results of SBFEM. The results of both methods are in very good agreement PB - Wiley-VCH Verl.
