The growing usage of elastic, piezoelectric and magneto-electro-elastic composites has
motivated the scientific and industrial communities to develop new numerical methods …

Compared to the traditional integer order viscoelastic model, a fractional order derivative
viscoelastic model is shown to be more accurate. A thorough knowledge of the dispersive …

Abstract Effects of initial stresses on the dispersion curves of Lamb and SH waves in
multilayered PZT-4/PZT-5A composites are investigated using the polynomial expansion …

Detecting the correct peaks of reflections in room impulse responses (RIRs) is of interest for
several applications. The time-of-flight (ToF) of these reflections peaks are needed, for …

In this paper, the attenuation of guided waves in damped multilayered arbitrary anisotropic
composite laminates is investigated using a Legendre orthogonal polynomial approach. The …

This paper presents a comparative study of different methods for obtaining the dispersion
curves of ultrasonic guided waves in anisotropic media. First, we present the classical …

A new spectral method based on the hybrid formula system of the state-vector and Legendre
polynomials are used to derive the explicit expressions of circumferential guided waves in …

We are considering the problem of reconstructing indoor temperature distributions using the
Acoustic travel-time TOMography (ATOM) technique. Motivated by the benefits of acoustic …

In this paper, the influence of an initial stresses on the Lamb waves propagation in an
anisotropic multilayered piezoelectric laminates is investigated. Formulations are given for …

Acoustic attenuation in piezoelectric composites is an important factor and it can be induced
by various sources, including viscoelasticity and semi-conductivity. Since the radio …
