Abstract

The majority of ultrasonic nondestructive testing applications in use today utilize longitudinal wave techniques. These are very effective for flaw detection and thickness measurement in scanning applications. In sheet and tube type materials, however, a more rapid technique has been developed utilizing Guided Wave Inspection. This method is capable of interrogating large areas of the material without extensive transducer scanning. An important requirement in this method is the ability to utilize relatively broad bandwidth transducers in the test. This paper presents the concepts on which Guided Wave Inspection is based as well as piezocomposite transducer incorporate a combination of piezoelectric ceramics and polymers to enhance the ultrasonic performance of the device. Additionally, the transducer can be designed to match to non-planar surfaces increasing its versatility when a difficult shape is involved.

Piezocomposites improve ultrasonic testing

Journal Article Meyer, P A - Advanced Materials and Processes

Ultrasonic testing is a nondestructive technique in which beams of high-frequency sound waves are introduced into materials for the detection of surface and subsurface flaws. Ultrasound probes--the devices that generate and receive acoustic energy--have historically been made of lead zirconate titanate (PZT) and similar piezoelectric ceramics. these materials have the capability to convert an electrical signal into acoustic energy (sound waves) to be transmitted into a part. The piezoelectric ceramic then converts the returning echoes into an electrical signal, which is evaluated by an electronic instrument similar to an oscilloscope. Although conventional transducers based on piezoelectric ceramics provide adequate performance,more »« less
Improved sound field penetration using piezocomposite transducers

Conference Meyer, P A

Ultrasonics has found widespread use in industrial and medical applications. Flaw detection, thickness measurement, and diagnostic imaging are just a few of the tools utilizing this technology. All information acquired by the ultrasound system passes through the transducer before being processed and presented to the operator. Therefore, the performance characteristics of the transducer can significantly influence system performance. In a previous presentation the author demonstrated that the incorporation of piezocomposites into transducer design yields a theoretical improvement of 4 to 10 dB in many applications. Prototype transducers constructed exemplified the expected improvements when used on low loss test materials. However,more »« less
Structural Diagnostics of CFRP Composite Aircraft Components by Ultrasonic Guided Waves and Built-In Piezoelectric Transducers

Thesis/Dissertation Matt, Howard M.

To monitor in-flight damage and reduce life-cycle costs associated with CFRP composite aircraft, an autonomous built-in structural health monitoring (SHM) system is preferred over conventional maintenance routines and schedules. This thesis investigates the use of ultrasonic guided waves and piezoelectric transducers for the identification and localization of damage/defects occurring within critical components of CFRP composite aircraft wings, mainly the wing skin-to-spar joints. The guided wave approach for structural diagnostics was demonstrated by the dual application of active and passive monitoring techniques. For active interrogation, the guided wave propagation problem was initially studied numerically by a semi-analytical finite element method, whichmore »« less

Ultrasonic guided wave inspection concepts for steam generator tubing

Journal Article Rose, J L ; Rajana, K M ; Carr, F T - Materials Evaluation; (United States)

Some very exciting and promising results have been obtained with respect to the utilization and guided wave techniques for inspecting steam generator tubing. In addition to some theoretical considerations that were studied recently, work has been carried out in special probe design and development. This special probe is used in demonstration of law detection feasibility, and in understanding the conceptual development of a complete flaw detection system. This includes transducer, pulser-receiver system, and appropriate signal processing and pattern recognition software for reliable inspection. Ultrasonic NDE techniques have progressed quite rapidly during this decade for two principal reasons: advanced signal processing,more »« less
Prototype Instrument for Noninvasive Ultrasonic Inspection and Indentification of Fluids in Sealed Containers
