Manufacturing defects and discontinuities in a product are anomalies which can lead to severe damages may sometimes involve loss of life. These must be examined corrected before the goes into service. There two methods testing for viz. Destructive Testing Non-Destructive Testing. entails subjecting conditions that leads failure whereas (NDT) is process examining products way it retains its usef...

Thin walled large structures are widely used for pipes, bridges, wings and body of aircrafts, and automobile bodies. To maintain such large structures, in addition to visual inspection, non-destructive testing with X-ray and ultrasonic is periodically implemented for essential parts. In ultrasonic non-destructive testing, ultrasonic pulse echo technique is generally used, in which plate thickne...

As the fuel efficiency of vehicles is being increased over the next decade due to both consumer demand and regulations, several automobile manufacturers are incorporating fiber-reinforced composites into their product line due to their high strength to weight ratio. While the fiber-reinforced components are lighter than the traditional aluminum and steel components, the processing and repair of...

al’s properties and acoustical characteristics have been studied for a long time and ultrasonic techniques have been used in non-destructive testing and imaging for decades. Ultrasound as an analytical tool has revolutionised diagnostics in medicine, but the application of ultrasound to material’s analyses has been held back by problems with ultrasonic design, electronics, sample handling, comp...

In the last decade, ultrasonic imaging systems have been an essential tool for diagnosis in medical and industrial applications, especially in the Non Destructive Testing area (NDT). Conventional ultrasonic imaging devices produce high quality images with good resolution and contrast. However, these machines are usually associated to a high cost in hardware resources, as well as in the time req...
