High suain rate tests have been carried out at both room temperature and 100°C on a Ti6A14V alloy using the torsional split Hopkinson pressure bar. An infrared radiometer has been developed to measure the surface temperature of the specimen during the high speed torsional test. Data have been obtained on the variation of stress with strain and strain rate at shear strain rates from 0.0007s" to ...

In this paper, Pulse Thermography analysis was applied to detect non emergent defects in asphalt concrete used for road pavements. Experimental and numerical experimentations were run on this specific heterogeneous material. Only experimental data acquired with an un-cooled microbolometer camera (less sensitive than a cooled one) were used. Data were processed using a semi-infinite heat transfe...

The sounding of the tendon ducts and rebars remains difficult due to their non accessibility and the important thickness of the cover concrete layer. This paper presents an active method to evaluate the poor filling of tendon ducts by way of active infrared thermography. This experiment is performed on two laboratory specimens. The experimental set-up depicts the non contacting heating techniqu...

ABSTRACT We present the discovery of TOI-2136 b, a sub-Neptune planet transiting nearby M4.5V-type star every 7.85 d, identified through photometric measurements from Transiting Exoplanet Survey Satellite (TESS) mission. The host is located 33 pc away with radius R* = 0.34 ± 0.02 R?, mass $0.34\pm \, \mathrm{M}_{\odot }$, and an effective temperature 3342 100 K. estimate its stellar rotation pe...
