TLDR
In this article, the authors provide a vision of ultrasonic guided wave inspection potential as we move forward into the new millennium and provide a brief description of the sensor and software technology that will make ultrasonic guidance wave inspection commonplace in the next century.Abstract:
Ultrasonic guided wave inspection is expanding rapidly to many different areas of manufacturing and in-service inspection. The purpose of this paper is to provide a vision of ultrasonic guided wave inspection potential aswe move forward into the new millennium. An increased understanding of the basic physics and wave mechanics associated with guided wave inspection has led to an increase in practical nondestructive evaluation and inspection problems. Some fundamental concepts and a number of different applications that are currently being considered will be presented in the paper along with a brief description of the sensor and software technology that will make ultrasonic guided wave inspection commonplace in the next century.read more

Preventing microbial biofilms on catheter tubes using ultrasonic guided waves
Huan-Lei Wang,Fengmeng Teng,Xin Yang,Xiasheng Guo,Juan Tu,Chunbing Zhang,Dong Zhang,Dong Zhang +7 more
TL;DR: A new anti-biofilm catheter prototype was proposed by combining an endotracheal tube with a group of ultrasonic guided wave (UGW) transducers to prevent bacteria aggregation with UGW vibrations, and sheds a light in the underlying mechanism of ultrasound-mediated biofilm prevention.

Quantification and localization of internal pipe damage
Bbsa Vogelaar,M Michael Golombok +1 more
TL;DR: In this article, the authors demonstrate pipeline integrity monitoring with only two single acoustic sensors mounted on the outer wall of a pipe and demonstrate that the pure torsional mode is the only wave that survives axisymmetric pipe reflection.

Finite element modelling of wave dispersion with dynamically consistent gradient elasticity
Terry Bennett,Harm Askes +1 more
TL;DR: In this paper, the authors investigated the discretisation aspects of a recently developed gradient elasticity model that is capable of describing wave dispersion and microstructural effects, including higher order stiffness terms alongside higher-order inertia terms.
