The paper provides a state of the art review of guided wave based structural health
monitoring (SHM). First, the fundamental concepts of guided wave propagation and its …

Condition-based maintenance refers to the installation of permanent sensors on a
structure/system. By means of early fault detection, severe damage can be avoided, allowing …

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 …

A survey of several methods under the heading of strong formulation finite element method
(SFEM) is presented. These approaches are distinguished from classical one, termed weak …

The growing use of composite materials for aerospace applications has resulted in the need
for quantitative methods to analyze composite components. Ultrasonic guided waves …

This paper presents experimental and theoretical analyses of the second harmonic
generation due to non-linear interaction of Lamb waves with a fatigue crack. Three …

Fiber reinforced polymer (FRP) composites have been widely used to retrofit RC structures,
such as with externally bonded FRP laminates (EB), externally bonded reinforcement on …

The detection and localization of structural damage in a stiffened skin-to-stringer composite
panel typical of modern aircraft construction can be addressed by ultrasonic-guided wave …

Ultrasonic guided waves have been used successfully in structural health monitoring
systems to detect damage in isotropic and composite materials with simple and complex …

This paper reviews the state-of-the-art in numerical wave propagation analysis. The main
focus in that regard is on guided wave-based structural health monitoring (SHM) …
