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 …

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 …

Steering flexural waves in thin plates benefits several applications, including vibration
energy harvesting and micro-electro-mechanical systems (MEMS). This study proposes a …

Probability-based diagnostic imaging, as one of the damage identification methods using
ultrasonic guided waves, has been attracting increasing attention by researchers in the …

Guided wavefield analysis methods for detection and quantification of crack damage in an
aluminum plate are presented in this paper. New wavenumber components created by …

This article presents a comprehensive review of the laser-based guided ultrasonic waves
propagation imaging (G-UPI) system and respective signal/data processing methods related …

There are two severe limitations of current flexural wave metasurface based on local
resonance mechanism or modal conversion method: low transmittance and only a single …

The spatial-wavenumber filtering technique is an effective approach to distinguish the
propagating direction and wave mode of Lamb wave in spatial-wavenumber domain …

Lamb wave propagation in the anisotropic material is characterized by the prominent
directivity of wave energy transfer governed by the fiber direction. Due to this anisotropic …

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 …
