Both A0 and S0 modes were analyzed in the frequency range of 50–300 kHz. Time of flight delays indicating a velocity decrease with increasing

Julia Albert,Herbert Reinke,Michael Wildthat propagate circumferentially around the pipe, known as CSH waves. Typically, a pair of transducers, a transmitter and a receiver, can be used to interrogate the whole circumference. Conventional shear horizontal transducers generate waves that propagate in both directions, namely, clockwise and c

Doing Modernity - Doing Religionstructures. The AU technology consists of sending and receiving low frequency acoustic pulses at a predetermined angle of incidence into a material under inspection. Analysis of the detected acoustic-ultrasound waveform characteristics provides a clear representation of the mechanical state of the s

VideojournalistInnen und das Fernsehpublikumnitoring (SHM) allows to ensure in real-time that aircraft substructures can still perform their function. Among all the technologies used in SHM, the emission/reception of Lamb waves are very popular. Algorithms using Lamb waves for damage detection and localization already exist in the literature

A Phenomenological Analysis of Approvalte structures. This article develops an accurate and computationally efficient time-domain spectral finite element (SFE) for wave propagation analysis of laminated composite and sandwich beam and panel-type structures based on the efficient layerwise zigzag theory. It considers the axial displacemen

Working the Natural/Artificial Distinctionthe group velocity is required; therefore, determination of accurate dispersion curves is invaluable. However, for complex materials, the wave speed is dependent on the propagation angle. From experimental observations of dispersion curves, measured using a two-dimensional Fourier transform, a syste
