8:30 - 9:15 AM:
Guided wave testing: past, present, and future
David Alleyne, GUL—Guided Ultrasonics Ltd. (United Kingdom)
Guided wave testing (GWT) and monitoring are evolving inspection and asset assessment methods that enable indirect measurement of thickness changes. This is a relatively new NDE method that has seen widespread industrial expansion in its use over the last two decades, primarily as an inspection solution for corrosion in pipes and pipelines. Corrosion represents a significant challenge in industrial pipelines and its presence and rate of growth is highly unpredictable and conditional on process and operating environments. This talk will chart the development of the enabling research at Imperial College into Lamb wave testing of pates from 1987 and its outcomes. The development of field useable equipment during the 1990’s allowed for the rapid development of the practical understanding of the complications that result from testing in-service piping. The talk will follow the evolution of the testing methodologies, international codes, standards and training schemes to support the global growth of this new NDE method. Over the last decade a short range quantitative guided wave scanning technique has been patented and recent advances using machine learning to automate the data analysis will also be introduced and discussed.
David Alleyne holds a PhD in Mechanical Engineering from Imperial College London. He has been the CEO of Guided Ultrasonics Ltd (GUL) since 2016, a company he co-founded in 1998. David has authored and been instrumental in many of the foundational patents relating to guided wave testing and monitoring, was pivotal in the 1999 introduction of long range testing using the torsional mode, and in the creation of the guided wave testing methodology, codes, standards, and Level 3 certification ever since. He has been the driver for the global commercialization of guided wave methods for over 30 years and is the acknowledged world leader in the industrial application of this technology.
9:15 - 10:00 AM:
Biologically inspired design
Akhlesh Lakhtakia, The Pennsylvania State Univ. (United States)
The bioworld is an immense repository of successful solutions to overcome problems. This repository can be used for biologically inspired design (BID), I will present various aspects of BID, including (i) identification of bioworld systems of relevance for engineering, with emphasis on multifunctionality, multicontrollability, sustainability, and circular economy; (ii) correlation of engineering problems with solution strategies available in the bioworld; and (iii) identification of pathways for systematic adaptation of bioworld strategies to solve engineering problems.
Akhlesh Lakhtakia obtained B.Tech. and D.Sc. in Electronics Engineering from Banaras Hindu University (BHU), and M.S. and Ph.D. in Electrical Engineering from University of Utah. He is now Evan Pugh University Professor and Charles Godfrey Binder Professor of Engineering Science and Mechanics, Pennsylvania State University. His current research interests lie in the electromagnetics of chiral and bianisotropic materials, sculptured thin films, electromagnetic surface waves, multicontrollable metasurfaces and mimumes, thin-film solar cells, biologically inspired design, and forensic identification. He has been elected a Fellow of OSA, SPIE, IoP, AAAS, APS, IEEE, RSC, and RSA.
He was the founding Editor-in-Chief of SPIE's Journal of Nanophotonics, VAJRA Professor at Indian Institute of Technology (BHU), and Otto Mønsted Visiting Professor at Danish Technical University. He has received the Penn State Faculty Scholar Medal in Engineering, SPIE Technical Achievement Award, SPIE Smart Structures and Materials Lifetime Achievement Award, Sigma Xi Walston Chubb Award for Innovation, IEEE APS Distinguished Achievement Award, and RCA Lifetime Achievement Award. He is a Jefferson Science Fellow at the US State Department in 2022-23.
