A method based on fitting the theoretical dispersion curves of Lamb waves to experimental
data is presented to determine the thickness and two independent elastic constants of …

We present a technique to measure the mechanical complex amplitude, ie the mechanical
amplitude and phase of vibration, of an ultrasonic plane wavefield of nanometric amplitude …

Lamb waves have shown to be favorably applicable in the development of health monitoring
systems in structural mechanics since they show reflections, refractions, as well as mode …

We describe the detection of bursts of surface acoustic waves by a double-pulsed TV
holography technique. We describe mathematically the long-and short-wave bursts in the …

In ultrasonic array imaging, 3D ultrasonic wavefields are normally recorded by an ultrasonic
piezo array transducer. Its performance is limited by the configuration and size of the array …

We present a novel capability of the TV holography technique applied to the non-destructive
testing of mechanical parts or structures with the form of a plate or a shell, which consists of …

We present a novel numerical modeling of ultrasonic Lamb and Rayleigh wave propagation
and scattering by through-thickness defects like holes and slots in homogeneous plates, and …

The composite materials have demonstrated an improvement in some properties, like the
weight, the durability, the corrosion resistance, and the sound and warmth insulation …

We describe a new technique, currently under development, intended to detect the presence
of flaws such as cracks and holes in thin-walled mechanical components. This technique …
