Acoustic black holes (ABHs) in beams and plates have been extensively studied as a
passive method for vibration attenuation and noise reduction. However, most research to …

In the last decades, several types of ABHs, ie circular, annular, and rectangular ABHs, have
been used for vibration attenuation. However, only the circular ABH has been studied for …

Abstract The Finite Element Method (FEM) is known to behave overly-stiff, which leads to an
imbalance between the mass and stiffness matrices within discretized systems. In this work …

Statistical modal energy distribution analysis (SmEdA) extends classical statistical energy
analysis (SEA) to the mid frequency range by establishing power balance equations …

Structural intensity fields provide a clear understanding of the noise, vibration and
harshness (NVH) behavior of complex structures by showing the vibration energy flow …

In the past decades, many researches have been done on the design optimization of low-
and high-frequency vibro-acoustic systems. However, the work of mid-frequency vibro …

Vibro-acoustic systems in aviation engineering could operate in a thermal environment and
suffer from high-frequency dynamic excitations. The high-frequency vibro-acoustic problems …

To calculate the specific transmission loss (TL) of a composite plate, the conjugate gradient
optimization method is utilized to estimate and optimize material properties of the composite …

In this paper, a new layout optimization technique is integrated with a statistical modal
energy distribution analysis (SmEdA) model to obtain the optimal layout of a porous sound …

Abstract MODal ENergy Analysis (MODENA) is an energy-based method, which is proposed
to deal with vibroacoustic problems. The performance of MODENA on the energy analysis of …
