Acoustic Transmission Loss Through Multilayer Periodic Elastic Structures

Application ID: 26841

In this model, two fluids are separated by a multilayer solid elastic structure. An acoustic pressure wave impacts the structure resulting in a reflected wave and a transmitted wave with a loss through the structure. This model investigates the transmission loss through the structure. The effects of incident angle, frequency, and damping is studied.

Important features used: Acoustic-structure interaction with arbitrary incident angle, scattered field formulation, the perfectly matched layer (PML), and periodic Floquet boundary conditions.

This model example illustrates applications of this type that would nominally be built using the following products:
