Acoustic metamaterials are known as a promising class of materials interacting with acoustic
and/or elastic waves. Band gap formation is one of the most spectacular phenomena that …

The characterization of propagation constants of realistic thin-walled structures with any
cross-section is studied in this paper. A propagative approach is proposed in order to extract …

A new approach called the “variational theory of complex rays”(VTCR) is developed for
calculating the vibrations of weakly damped elastic structures in the medium‐frequency …

An exact dynamic stiffness matrix for a beam is developed by integrating the Rayleigh–Love
theory for longitudinal vibration into the Timoshenko theory for bending vibration. In the …

Prediction and measurement of vibration power flow in structures are both important for
locating vibration sources and sinks and for confirming vibration propagating paths. From …

Why it is difficult to solve a vibroacoustic problem; what are the hidden pitfalls that one is
called to overcome; are there methods or techniques suggested in other fields of physics …

The frequency-dependent mass, elastic and geometric stiffness matrices of an axially loaded
Bernoulli-Euler beam are developed through rigorous application of symbolic computation …

In this note numerical sensitivity of a wave finite element approach and its post processing
for group velocities and energy velocities estimation is dealt with. Precisely, aliasing effects …

The energy flow analysis method used to predict the structural vibration response and the
radiated sound power of a plate excited by wall pressure fluctuations under turbulent …

Starting from the solutions of the governing differential equations of motion in free vibration,
the frequency dependent mass and stiffness matrices of bar and beam elements have been …
