Journal ArticleDOI
Characterization of surface cracks with Rayleigh waves: a numerical model
TL;DR: In this paper, a numerical model is adapted from earth physics in order to better understand the influence of the crack geometry on Rayleigh-wave propagation, based on an indirect boundary element method, calculates the threedimensional seismic response of two-dimensional structures.
Journal ArticleDOI
Study of stress-induced velocity variation in concrete under direct tensile force and monitoring of the damage level by using thermally-compensated Coda Wave Interferometry.
Yuxiang Zhang,Odile Abraham,Frédéric Grondin,Ahmed Loukili,Vincent Tournat,Alain Le Duff,Bertrand Lascoup,Olivier Durand +7 more
TL;DR: This work program includes a creep test with a sustained, high tensile load; the acoustoelastic coefficients are estimated before and after conducting the creep test and then used to demonstrate the effect of creep load.
Journal ArticleDOI
2D elastic full-waveform imaging of the near-surface: application to synthetic and physical modelling data sets
TL;DR: In this article, a two-dimensional full-waveform inversion of land seismic data, based on frequency-domain viscoelastic modelling, is proposed to take advantage of the full complexity of seismograms and simultaneously build 2D images of P and VS parameters.
Journal ArticleDOI
Small crack detection in cementitious materials using nonlinear coda wave modulation
Benoit Hilloulin,Yuxiang Zhang,Yuxiang Zhang,Yuxiang Zhang,Odile Abraham,Ahmed Loukili,Frédéric Grondin,Olivier Durand,Vincent Tournat +8 more
TL;DR: In this paper, an ultrasonic method based on the nonlinear acoustic mixing of coda waves with lower-frequency swept pump waves was proposed for detecting small cracks in cementitious materials.
Journal ArticleDOI
Validation of a thermal bias control technique for Coda Wave Interferometry (CWI)
Yuxiang Zhang,Odile Abraham,Vincent Tournat,Alain Le Duff,Bertrand Lascoup,Ahmed Loukili,Frédéric Grondin,Olivier Durand +7 more
TL;DR: A bias control technique involving the use of a second (reference) specimen for CWI analysis that is designed to compensate the thermally-induced velocity variation due to environmental temperature fluctuations and bias originating from experimental procedures is offered.
