Lamb wave is widely recognized as one of the most encouraging tools for structural health
monitoring (SHM) systems. In spite of many favourable characteristics of Lamb wave for …

The early work on long range guided wave nondestructive testing (NDT) was largely done in
industry, and multiple applications were developed before a surge in academic interest …

Ultrasonic-based non-destructive testing technologies have been extensively applied for
detection of internal damage in concrete. However, it is vulnerable to environmental …

The successful implementation of Structural Health Monitoring (SHM) systems is confined to
the capability of evaluating their performance, reliability, and durability. Although there are …

This paper presents a deep learning network that performs automatic detection of defects by
inspecting full ultrasonic guided wave signals excited in plate structures. The findings show …

To account for the temperature effect on guided wave signals in complex structures, a
significant amount of baseline measurements typically need to be collected over a large …

Guided wave ultrasonics is an attractive monitoring technique for damage diagnosis in large-
scale plate and pipe structures. Damage can be detected by comparing incoming records …

This article investigates the role of ambient temperature in causing changes to the structural
wave propagation, as sensed by piezoelectric transducers, in a newer perspective. A novel …

An experimental monitoring system was installed on an operational heavy haul rail track.
The system used two piezoelectric transducers mounted under the head of the rail to …
