While improvements in instrumentation have moved ultrasonic testing technology into more areas, ... and reflecting the sound wave from its interior surface to produce a precise measurement of wall ...

While there has been considerable research into diagnosis methods for steel pipes such as radiography, ultrasonic testing, visual inspection and ground penetrating radar, Master of Applied Science ...

An ultrasonic shear (transverse) wave entering a stressed solid body splits up into two components travelling at different velocities depending on the relevant elastic ‘constants’ which are ...

The bottom surface of a component cannot be used for bouncing back longitudinal waves when this surface is coated with a CRA. To overcome the challenges in the inspection of the uppermost section of a ...

The team experimented in the lab with lead, copper, steel and polyvinyl chloride (PVC) pipes, using piezoelectric accelerometer sensors to record stress wave propagation through each when struck with ...
