Determination of Young's Modulus of a metallic bar using traveler pulse detection by fiber optic sensors type LPG

EasyChair Preprint 1191

Abstract

Two fiber optic accelerometers LPG were glued on the surface of a metal rod simply supported at its ends. Transverse and longitudinal pulses were excited at one end of the rule. The sensors were placed near the ends of the rod. Step pulse is detected by each LPG sensor. Measuring the distance between the sensors and travel time pulse, the transmission speeds longitudinal and transverse pulses are determined, from which is the estimated value of the elastic modulus of the metal rod.

Keyphrases: LPG fiber optic sensors, monitoring of structural damage, propagation of waves in solids
