汇报题目:参加QNDE 2018国际会议总结报告会

汇报时间2018723(星期一) 14:30

汇报地点:科技园西五楼南205会议室

汇报人:邵永胜

会议名称45thAnnual Review of Progress in Quantitative Nondestructive Evaluation

会议时间July15-19,2018

会议地点Burlington, Vermont, USA

会议简介QNDE is a highly interdisciplinary technology that involves the use of various techniques to detect both manufacturing and service related flaws in materials and structures which are important to safety in essentially all industries. The Annual Review is a week-long technical meeting in which both advances in fundamental knowledge and new engineering applications in several measurement technologies - ultrasonics, eddy currents,X-rays, thermosonics and thermography, among others - are reported and discussed. For more than four decades, the QNDE Conference has been identified as the world's leading research/engineering conference in this specialized engineering field.

Title: Trailing Waves for Nondestructive Testing of Thick Plates

Author: Yongsheng Shao and Jing Lin

Abstract: Traditionally, Lamb waves and bulk waves are two main means of ultrasonic-based damagedetection for plates [1, 2]. Trailing waves are the transition state of Lamb waves and bulk wavesand generated by elastic waves propagating in plates at large frequency thickness product. Theyperform like a list of longitudinal waves with constant time delay. The phase relationship andamplitude distribution of pulses in trailing waves are discussed. Trailing waves have uniqueadvantages of high resolution and high efficiency for the detection of thick plates. However, thesplit of waves complicate the interpretation of signals. We propose a compression method topurify the pulse train. The accurate time delay of defects are obtained. It proves that trailingwaves can complete the detection efficiently and effectively.
