In this paper we review recent progress on the analysis, experimental exploration, and
application of elastic wave propagation in weakly nonlinear media and metamaterials. We …

Fatigue damage is difficult to detect and evaluate non-destructively, specifically at its early
stages (before the macro-crack formation). In this study, fatigue damage is evaluated based …

Various techniques have emerged in the past few years for localizing the acoustic source in
an anisotropic plate. The wave front shape-based approach, one of the recent additions to …

Monitoring material degradation and in-service damage in fibrous composites at an early
stage is challenging, yet critical for many industrial applications. Second harmonic Lamb …

Ultrasonic inspection is a well recognized technique for non-destructive testing of aircraft
components. It provides both local highly sensitive inspection in the vicinity of the sensor …

Lamb waves have infinite number dispersion modes; however, no every mode is excitable
and detectable. Traditional matrix methods can calculate the dispersion curve of each mode …

The paper presents a method for the estimation of true spectral characteristics and for the
analysis of numerical models for guided waves. The proposed procedure makes use of a …

In this work, homogenisation of textile composite models is studied in order to increase the
accuracy of wave dispersion predictions in such complex structures. A multiscale …

Acoustic emission (AE) technique, which uses the occurrence of AE phenomena, is a
powerful monitoring tool that finds tremendous applications in engineering. Owing to the …

The employment of guided waves for structural health monitoring applications has attracted
substantial attention in recent years. Piezoelectric transducers are frequently employed in …
