Development of omni-direction shear-horizontal wave magnetostrictive transducer for NDE applications
Non-destructive evaluation (NDE) is to be used to inspect a material for flaws. One of the methods of NDE is ultrasonic testing and it can detect in-depth flaws of most materials, as long as they can conduct sound. The concept of ultrasonic testing is whereby ultrasonic transducers convert various t...
