The modern scope of boundary element methods (BEM) for acoustics is reviewed in this
paper. Over the last decades the BEM has gained popularity despite suffering from …

While acoustic black holes (ABHs) are well-known inefficient at low frequencies. However,
attaching periodic local resonators to form a metamaterial ABH (MMABH) plate could be …

Annular acoustic black holes (ABHs) have been recently proposed as a potential means for
reducing vibrations of cylindrical shells. The latter are very common structures in the naval …

In this paper, we consider a composite cylindrical shell having an internal thin plate. When
some ABHs are embedded on the interior floor, the vibration of the cylindrical shell and the …

This chapter presents an introduction to the solution of time-harmonic acoustic problems by
a boundary element method (BEM). Specifically, the Helmholtz equation with admittance …

Vibrating structures have received considerable critical attention as they radiate sound into
enclosures where it is amplified by reflections. Surface and panel contribution analyses …

Localisation of sound sources on vibrating structures is a critical part of the design in many
engineering applications. In structures with stiffeners, so-called Bloch–Floquet waves are …

Sound radiation from vibrating structures is a crucial concern in the vehicle design process.
One effective tool to recover vibration patterns on surfaces is the surface contribution …

The non-negative intensity (NNI) method is applied to large-scale coupled fluid–structure
interaction (FSI) problems using the fast multipole boundary element method (FMBEM). The …

Identification of regions on a vibrating structure which radiate energy to the far field is critical
in many areas of engineering. Non-negative intensity is a means to visualize contributions of …
