Structural Health Monitoring of Aerospace Composite Structures offers a comprehensive
review of established and promising technologies under development in the emerging area …

This article presents a review of air-coupled ultrasonics employed in the characterization or
nondestructive inspection of industrial materials. Developments in air-coupled transduction …

This study investigates the time reversal process (TRP) of Lamb wave signals which are
transmitted and received by piezoelectric transducers bonded on plate-like structures. A …

Abstract Shear-Horizontally (SH) polarized, ultrasonic, guided wave modes are considered
in order to infer changes in the adhesive properties at several interfaces located within an …

The monitoring of adhesively bonded joints by ultrasonic guided waves is the general topic
of this paper. Specifically, composite-to-composite joints representative of the wing skin-to …

In this study an inverse procedure based on the propagation of guided ultrasonic waves is
proposed for the characterization of the elastic material constants of plates. The procedure …

Many engineering structural elements make use of adhesively bonded joints due to its
lighter weight, load distribution and transmission mechanisms. The safety of the structure …

Adhesive bonding is widely used in aerospace composite structures. A continuous well-
cured bond can offer good joint strength and improved fatigue and impact resistance, and is …

The sensitivity of Lamb wave modes to a particular defect or instance of damage is
dependent on various factors (eg, the local strain energy density due to that wave mode). As …

This article deals with the monitoring of the composite wing skin-to-spar joint in unmanned
aerial vehicles using ultrasonic guided waves. The study investigates simulated wing skin-to …
