Digital NDT (Non Destructive Testing)

IFAC Proceedings Volumes, 1995
Abstract The objective of this work was to improve the electronics of an NDT(disperse magnetic flux) equipment by means of real time digital processing of the signals coming from the field, thus increasing reliability, precision, accuracy and decreasing calibration times. An electronic defect simulator was built in order to obtain signals similar to

Non destructive testing (NDT) with high Tc RF SQUIDs

Journal of Physics: Conference Series, 2008
A high Tc rf SQUID nondestructive evaluation (NDE) set-up has been realized to measure the eddy current induced field in different aluminum samples, under a weak AC and low frequency magnetic excitation. An efficient and simple analytic modeling method has been also developed for computing the magnetic field created by the induced eddy current in the ...

Probabilistic estimation of reliable sensor spacing for wire break detection in prestressed concrete using acoustic emission technique

Structural Concrete, EarlyView.
Abstract The acoustic emission (AE) technique has proven to be an effective method for detecting individual wire breaks in prestressed concrete structures affected by stress corrosion cracking (SCC). However, despite its widespread application, the quantitative assessment of AE monitoring reliability and optimal sensor placement remains unresolved ...
