Application of 2D elastic Rayleigh waveform inversion to ultrasonic laboratory and field data

Abstract: In addition to geophysical applications from the near surface to a global scale, seismic full‐waveform inversion can be applied to ultrasonic data on the centimetre and decimetre scales for nondestructive testing of pavements, facades, plaster, sculptures, and load‐bearing structures such as pillars or core samples from boreholes, which can consist of geo‐materials and non‐geomaterials. Classical non‐destructive testing approaches are based on the inversion of body‐wave travel times to deduce P‐wave velocity m… Show more

“…1). Based on full-wavefield modeling, FWI is able to fully exploit the waveform information and is getting increasingly popular on continental (Fichtner et al 2008), explorational , near-surface (Groos et al 2017), and laboratory (Köhn et al 2016) scales. Due to the specific wavefield characteristics (e.g., frequency range and wave type) and recording systems in each scale, the successful application of FWI on different scales is not simply a matter of scale.…”

“…Furthermore, Xia et al [27] and Shao et al [28] extended the tomographic approach to the detection of near-surface shallow cavities. Köhn et al [29] used a similar inversion method to reconstruct surface layer stiffness of an ancient sandstone façade. Chen et al [30] adopted an inversion procedure to detect residual stresses from general Rayleigh wave dispersion of a weakly anisotropic media.…”

“…Chen et al [30] adopted an inversion procedure to detect residual stresses from general Rayleigh wave dispersion of a weakly anisotropic media. These methods stem from wave signal processing theories (in earlier works [27,28]) or discretized equations of motion (in later works [29,30]). Through the formulation of an "operator matrix" of inverse problem, the researchers try to find an optimum solution of the "model vector" that is feasible to the "data set".…”

“…On the ultrasonic scale Bretaudeau et al (2013) reconstructed the Pand S-wave velocity model of a physical scale model by a FWI of surface and body wave data. Köhn et al (2016) used single-folded ultrasonic Rayleigh waveform inversion to map 2D near-surface S-wave velocity variations due to weathering effects at the Porta Nigra in Trier (Germany). Schäfer (2014) applied a multi-parameter 2D Rayleigh-FWI including density to a seismic line over a thrust fault.…”
