Prof Jean-Yves Buffiere, INSA, Université de Lyon
Image based simulation of damage development in metals under mechanical loading
Jean-Yves Buffiere graduated from Grenoble Institut National Polytechnique (INP) in 1989. After a PhD also in Grenoble (1993) and a Post Doc at Imperial College in London he was appointed Associate Professor at Institut National des Sciences Appliquées de Lyon (INSA LYON) in 1994. Since 2003 he is a Professor of Materials Science at INSA (Mechanical Engineering Department). The main focus of his research is on the characterization of damage in advanced metallic materials submitted to mechanical loading. Through collaborations with several synchrotron sources, among which the European Synchrotron Facility (ESRF) in Grenoble, he has pioneered the use of high resolution synchrotron X ray tomography for the non destructive 3D characterization of materials. He has supervised or co-supervised more than 30 PhD projects and post doctoral research programs in the field of fatigue of metals and three dimensional characterization; he is the co-author of more than a 150 papers on that topic and the co-author of a book on 3D Imaging in Mechanics of Materials (Hermes ed. ).
Dr Chu Lun Alex Leung, University College London
Seeing inside powder bed fusion with X-ray imaging and image-based modelling
Dr. Chu Lun Alex Leung is a Lecturer in Imaging of Advanced Materials and Manufacturing in the Department of Mechanical Engineering at University College London (UCL). Dr. Leung and Prof. Lee are co-leading the Materials, Structure, Manufacturing group at Harwell (MSM@H), UCL, UK Leung's research focuses on the development of intelligent advanced manufacturing using cutting-edge sensing technologies, including ultra-fast X-ray imaging, X-ray computed tomography and image-based modelling. Before his appointment, he worked as a Postdoctoral Research Fellow at UCL (2018 - 2019) and a Research Associate (2013 - 2017) in the Department of Materials at the University of Manchester, where he obtained his Ph.D. in Materials (2018). His thesis: "X-ray imaging of powder consolidation during laser additive manufacturing" led him to receive 5 individual awards, including the Sir Richard Brook prize (Best Engineering Ph.D. in the UK) sponsored by the Centre for Advanced Structural Ceramics and the Winner of the European Powder Metallurgy Association (EPMA) PM Thesis Competition 2019 sponsored by Högänas AB. Leung has also worked for British Steel (formerly known as Tata Steel Europe) and his last role was working as a New Product Development Project Manager (2011 - 2013). Besides his industrial experience, he earned a Design London fellowship (2009 - 2011) funded by Imperial College London and the Royal College of Art and worked on a product prototype using directable light technology. He received a First Class Honour degree in Aerospace Materials (MEng) and David West prize (2010) from the Department of Materials, Imperial College London.
Special Invited Speaker
Dr Tim J. Barden, Rolls-Royce plc
Sensors and sensing - Getting to the start line for imaged-based simulation
Tim Barden moved to Rolls-Royce having carried out a post-doctorial position at Bath University researching thermal methods for non-destructive evaluation. His role at Rolls-Royce primarily involves the development and introduction of new NDE technologies and is the current Industrial Chair of the Research Centre in Non-Destructive Evaluation.
Image based simulation has potential benefits to many industries. However, as with all simulation, understanding the inputs is essential and for image based simulation they are varied and each application will have its own limitations. Non-destructive evaluation (NDE) utilises a wide scope of technologies, any physical phenomena that gives information about material integrity could be used as a NDE technique. The same can be said for obtaining data for image based simulation. Modalities include the electromagnetic spectrum, such as optical and x-rays, as well as vibrational waves such as ultrasonics. The variation is further increased by the numerous techniques to stimulate a test object, monitor the response and interpret the output.
The presentation will concentrate on the more common NDE techniques used for obtaining image data including radiography, x-ray computed tomography, ultrasonic and visual. Additionally, general topics will be considered including understanding the quality of the data and reducing artefacts.
Training Session Leaders
Nicolas Piché, PhD, Vice President, Research & Development, ORS
Dr Piché brings more than 25 years of industry and academic leadership experience to this role. He was instrumental in the development of the company's core imaging platforms and currently leads the research team that is translating the promise of deep learning into transformative solutions for imaging applications. Prior to co-founding ORS, Dr Nicolas Piché held senior positions in prominent North American and European technology companies and has authored papers within the field of image processing, microanalysis, deep learning, and medical imaging. Dr Piché earned his PhD at École Polytechnique de Montréal.
Mike Marsh, PhD, Director of Product Management, ORS
Dr Marsh earned his PhD in Structural and Computational Biology from Baylor College of Medicine. He has worked in imaging technology and solutions, with an emphasis on 3D visualization and analysis, for over 15 years. His academic training was in biological sciences, but he has been tasked to develop other areas of expertise for commercial development, including materials sciences and geosciences. This expertise has led to contributed book chapters, review articles or invited talks spanning these multiple disciplines. His scientific imaging and image processing covers X-ray CT, TEM, SEM and SEM-related microanalysis. For the last four years, Dr Marsh has worked as the Dragonfly Product Manager at Object Research Systems.
Dr Emrah Sozumert, ZCCE, Swansea University
Dr Emrah Sozumert is a postdoctoral researcher at the Zienkiewicz Centre for Computational Engineering at Swansea University. He is currently working on Inline virtual qualification from 3D X-ray imaging for high-value manufacturing funded by EPSRC (2020-2023). He was awarded a PhD by Wolfson School of Mechanical, Electrical and Manufacturing Engineering at Loughborough University. His PhD research was on multi-scale modelling of polymeric nonwovens, financially supported by Loughborough and North Carolina State Universities. His research interests are image-based modelling, finite-element method, random fibrous networks.
Rhydian Lewis, ZCCE, Swansea University
Rhydian Lewis is a PhD student at Swansea University. His research is in collaboration with the UK Atomic Energy Authority (UKAEA) to maximise the impact of a testing facility through coupling experimental and simulation data. The aim is to use Machine Learning (ML) to analyse and monitor the physical results and those of the Virtual Twin (VT) counterpart for a better understanding. Rhydian completed his bachelor’s degree in Mathematics and its Applications in Cardiff University in 2014 and a master’s degree in Aerospace Engineering at Swansea University in 2018 before joining the IBSim group at the start of 2019.
