Damage identification of wind turbine blades based on deep learning and ultrasonic testing
Nondestructive Testing and EvaluationUltrasonic testing (UT) is an effective method for detecting internal damage in wind turbine blades. However, manual interpretation is time-consuming and subjective.

DFW-YOLO: YOLOv5-based algorithm using phased array ultrasonic testing for weld defect recognition
Nondestructive Testing and EvaluationAlthough phased array ultrasonic testing (PAUT) technology has been widely employed in pipeline weld defect recognition, current defect recognition still relies on manual operation, which limits its efficiency.

Comparison of Laser Ultrasonic Testing and traditional Ultrasonic Testing
Proceedings of the Annual British Conference on Non-Destructive TestingUltrasonic inspection is a widely accepted method in the aerospace industry for detecting defects and characterizing materials. However, the traditional ultrasonic technique requires precise alignment and couplant between the ultrasonic scanner and the ...

Automated ultrasonic testing for near-surface flaws in CFRP
Nondestructive Testing and EvaluationIn ultrasonic testing of Carbon Fiber Reinforced Polymers (CFRP), signals of near-surface flaws are often submerged in interface signals, resulting in blind spots for defect detection. To address this issue, this paper presents an autocorrelation imaging

Ultrasonic measurement of canine testes
Theriogenology, 1993The goals of the present study were to determine if ultrasonic measurement of testicular dimensions (length, width, and height) would provide an accurate assessment of canine testicular size (weight) and to determine the relationship of these measurements to animal body weight.

Ultrasonic testing of reactive powder concrete
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2004Concrete is a critical material for the construction of infrastructure facilities throughout the world. Traditional concretes consist of cement paste and aggregates ranging in size from 6 to 25 mm that form a heterogeneous material with substantial compressive strength and a very low tensile strength.

Ultrasonics, 1963
Abstract From the earliest days of materials testing by ultrasonics to find internal flaws it has been possible to locate quite small defects. Today the sensitivity of the testing instrument has increased so much that in many instances the minimum size of internal defects which can be located is limited chiefly by the grain size of the material under
