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 …

The paper introduces a novel method for simulating acoustic–shell interaction subject to
seabed reflection. The vibration of thin-shell structure is analyzed using the finite element …

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 …

This paper presents a novel method for topology optimization of vibrating structures
interacted with acoustic wave for the purpose of minimizing radiated sound power level. We …

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 …

A novel boundary element method based on subdivision surfaces is applied to simulate
wave scattering problems governed by the Helmholtz equation. The Loop subdivision …

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 …

A combined shape and topology optimization algorithm based on isogeometric boundary
element method for 3D acoustics is developed in this study. The key treatment involves …
