Abstract

The position of a macrocrack within a circular tube can be determined through the periodic energy distribution variation of a linear non-axisymmetric guided wave. However, to determine the positions of a microcrack within a circular tube is still a difficult job, even for the nonlinear guided wave. Unlike the linear guided wave can detect the axial position through the reflection from a macrocrack, a fatigue crack does not even cause remarkable reflection. This paper investigates the energy concentration degree periodical variation rule of fatigue crack-induced second harmonic non-axisymmetric guided wave within a circular tube. The quantitative relationship between the energy concentration degree and its propagated axial distance is potential to be used to detect a fatigue crack and characterize its axial, circumferential positions. To facilitate the investigation, a specific frequency extracting method was optimized to extract the second harmonic non-axisymmetric guided wave. In addition, an energy concentration degree coefficient was designed to characterize the energy distribution. The fundamental, numerical and experimental work were implemented to verify the studied energy concentration degree periodical variation rule.

期刊介绍： NDT&E international publishes peer-reviewed results of original research and development in all categories of the fields of nondestructive testing and evaluation including ultrasonics, electromagnetics, radiography, optical and thermal methods. In addition to traditional NDE topics, the emerging technology area of inspection of civil structures and materials is also emphasized. The journal publishes original papers on research and development of new inspection techniques and methods, as well as on novel and innovative applications of established methods. Papers on NDE sensors and their applications both for inspection and process control, as well as papers describing novel NDE systems for structural health monitoring and their performance in industrial settings are also considered. Other regular features include international news, new equipment and a calendar of forthcoming worldwide meetings. This journal is listed in Current Contents.
