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 …

We propose a method to simultaneously determine the thickness of an isotropic plate
together with the longitudinal and shear elastic wave velocities of its material. The method …

We propose a method for nondestructive characterization of progressive fatigue damage in
solid plates, using a zero-group-velocity (ZGV) Lamb mode generated and detected by …

In this paper, a non-contact non-destructive evaluation of cumulative fatigue damage in 75 μ
m-thick aluminum plates is conducted by using the first symmetric zero-group-velocity Lamb …

We present an evaluation of attenuation of elastic waves in the GHz range, based on the
decay of thickness-stretch resonances of plates. We measured the elastic response of micro …

Zero group velocity (ZGV) Lamb modes have already shown their potential in nondestructive
testing applications as they are sensitive to the sample structural characteristics. In this …

Lamb modes with zero group velocity at nonzero wave numbers correspond to local and
stationary resonances in isotropic plates. Lamb modes can be utilized for nondestructive …

Elastic waves are used in fields as diverse as the non-destructive evaluation of materials,
medicine, seismology and telecommunications. Elastic Waves in Solids 1 presents the …

The intersections between Lamb mode dispersion curves of free isotropic plates at real
values of frequency and wave number are examined for the full allowed range of Poisson's …

In this paper, we present a method to recover the complex wavenumber dispersion relations
using spatial Laplace transform from experimental spatiotemporal signals measured by …
