Quality Assurance in NDT

The importance of Nondestructive Testing (NDT) as a Quality Control/ Quality Assurance tool in the industrial domain cannot be over-emphasized. With the rapid advancement in research and technology, the NDT field is becoming larger and more sophisticated day by day. Innovative research in materials science and digital technology is paving the way for more and more new methods in NDT technology....

PVF2 Transducers for NDT

We have investigated the spatial dependence of the longitudinal piezoelectric stress constant e of PVF . Experiments were performed on a series of no.minally identical brass-backed PVF longitudinaF wave t~ansducers in water using commercial PVF7 film. Computer programs were designed t6 predict the performance of the transducers as a function of e (Z) , the thickness mode piezoelectric stress co...

Recent Developments in Ndt Simulation

Since the beginning of the nineties, the CEA (the French Atomic Energy Commisssion), has been being developing ultrasonic modeling tools dedicated to NDT simulation and, over the years, integrated in the CIVA software platform. The models allow to compute ultrasonic beams generated by transducers in the inspected components, to conceive phased arrays transducers and to predict echoes arising fr...
