Optimization of phased-array transducers for ultrasonic inspection in composite materials using sliding probes
The increasing use in the industries of composite materials implies finding a suitable way for testing and evaluating them. Non-destructive testing by ultrasounds is an appropriate method to detect defects in this type of materials, however, because of their structure it is required to find the most applicable and accurate process for detecting flaws and anomalies in them. For conventional ultr...
متن کاملUltrasonic phased array inspection of electrofusion joints in polyethylene pipes
The use of plastic as a pipe material for the transport of gas and water has increased over the last few years, attributed to the significant advantages of this material such as corrosion resistance, strengthto-weight ratio, lightness, flexibility and cost. Consequently, these pipes have a long predicted service life. One of the pipes’ joining processes is electrofusion welding. As for all kind...
متن کاملGroundwork for Rail Flaw Detection Using Ultrasonic Phased Array Inspection
An apparent increase in the detectability of certain flaws results when the ultrasonic inspection beam was oriented off the longitudinal axis of railroad rail. Here, artificial reflectors were used to better define the extent of material "seen" by inspection beams, and determine how surface curvature might affect the inspection. Presumably, such information could be useful for suggesting optimu...
متن کاملUltrasonic nondestructive inspection of solid objects
Ultrasonic testing (UT) has been used for nondestructive evaluation (NDE) of materials for more than half a century. A number of NDE techniques have been developed and specifi standards have been created for the UT applications in different areas of engineering. UT has two main goals related to inspection of solid objects, firstl , detection and characterization of material discontinuities (fl ...
متن کاملBiplane Phased Array for Ultrasonic Medical Imaging
We report a transducer structure tha t combines two orthogonal phased arrays which enable the real-time scanning of two orthogonal sectors. This biplane phased array is formed by partially dicing the opposite faces of a composite piezoelectric plate in orthogonal directions. Individual elements of the orthogonal arrays show broad radiation patterns close to the theoretical expectations for isol...
