Detection of chemical damage in concrete using ultrasound

S. Ould Naffa, Marc Goueygou, Bogdan Piwakowski, François Buyle-Bodin

This research deals with a non-destructive method for characterizing the degraded cover of concrete structures using high-frequency ultrasound (0.5–1 MHz). Although such a frequency range is unusual in civil engineering, it is well suited to the kind of defect to be detected, as it corresponds to a…

Assessment of broadhand ultrasonic attenuation measurements in inhomogeneous media

Marc Goueygou, Bogdan Piwakowski, S. Ould Naffa, François Buyle-Bodin

In this paper, we address the problem of evaluating the acoustic attenuation of “difficult” media, i.e. highly attenuating and scattering media. In a broadband, through transmission setup, the signals acquired from such media are characterized by a poor signal-to-noise ratio. Therefore, an accurate…

Study of adhesive forces on a silicon nanotip force microscope in contact mode

Vincent Agache, Bernard Legrand, Dominique Collard, Lionel Buchaillot

Atomic Force Microscope operating in contact mode is used in this paper for probing the spatial distribution of adhesive forces versus the topography of a silicon nanotip. This nanotip consists in an ultra sha4rp silicon tip with radius less than 15 nm fabricated using a combination of high-…
