Ultrasonic monitoring of stress and cracks of the 1/3 scale mock-up of nuclear reactor concrete containment structure
Qi Xue, Eric Larose, Ludovic Moreau +3
To evaluate the stress level and damage of a reinforced concrete containment wall and its reaction to pressure variations, we implemented successive ultrasonic experiments on the e…
On the precision of noise correlation interferometry
Richard L Weaver, Céline Hadziioannou, Eric Larose +1
Long duration noisy-looking waveforms such as those obtained in randomly multiply scattering and reverberant media are complex; they resist direct interpretation. Nevertheless, suc…
Locating a weak change using diffuse waves (LOCADIFF) : theoretical approach and inversion procedure
Vincent Rossetto, Ludovic Margerin, Thomas Planès +1
We describe a time-resolved monitoring technique for heterogeneous media. Our approach is based on the spatial variations of the cross-coherence of coda waveforms acquired at fixed…
Stability of Monitoring Weak Changes in Multiply Scattering Media with Ambient Noise Correlation: Laboratory Experiments
Céline Hadziioannou, Eric Larose, Olivier Coutant +2
Previous studies have shown that small changes can be monitored in a scattering medium by observing phase shifts in the coda. Passive monitoring of weak changes through ambient noi…
Monitoring stress related velocity variation in concrete with a relative resolution using diffuse ultrasound
Eric Larose, Stephen Hall
Ultrasonic waves propagating in solids have stress-dependent velocities. The relation between stress (or strain) and velocity forms the basis of non-linear acoustics. In homogeneou…
Fluctuations of correlations and Green's function reconstruction: role of scattering
Eric Larose, Arnaud Derode, Philippe Roux +1
Correlations of ambient seismic or acoustic vibrations are now widely used to reconstruct the impulse response between two passive receivers as if a source was placed at one of the…
