Reihe: Advanced Structured Materials

This book presents recent material science-based and mechanical analysis-based advances in joining processes. It includes all related processes, e.g. friction stir welding, joining by plastic deformation, laser welding, clinch joining, and adhesive bonding, as well as hybrid joints. It gathers selected full-length papers from the 1st Conference on Advanced Joining Processes.

Prof. Lucas F. M. da Silva completed his Ph.D. at the University of Bristol (UK) in 2004. He is currently a Full Professor at the Faculty of Engineering, University of Porto (FEUP). His research is focused on the production and design of adhesive joints. He is the Director of the Integrated Master in Mechanical Engineering at FEUP and President of the Portuguese Adhesion Society.
He is the author or editor of 18 research books, 34 book chapters, and over 250 ISI-indexed papers. One of his papers was awarded the SAGE Best Paper Award 2010 and Donald Julius Groen Prize 2010 (both awards are granted by the Institution of Mechanical Engineers (IMechE)). He received the FEUP Scientific Excellence Award in 2013 and a second time in 2018.
He is Editor-in-Chief of several journals, and has founded and chairs various conferences on adhesion (Structural Adhesive Bonding, Luso-Brazilian Conference of Adhesion and Adhesives and Industrial Applications of Adhesives), joining processes (Advanced Joining Processes), materials (Materials Design and Applications) and education (Science and Technology Education). Paulo A. F. Martins is a Professor of Manufacturing at the University of Lisbon, doctor technices honoris causa at the Technical University of Denmark, member of the International Academy for Production Engineering (CIRP), and advisor member of the Standing Advisory Board of the International Conference on Technology of Plasticity (ICTP). He is the co-author of six books, holds several international patents, and has published over 400 papers in international journals and conference proceedings. His main research interest is in manufacturing - especially numerical and experimental analysis, and the development of forming and joining by forming processes. Mohamad S. El-Zein, Ph.D. Engineering Mechanics, is a John Deere Fellow in materials. He has had various areas of responsibility at Deere, including structural analysis, analytical tools, composites and plastics, fatigue, high-performance computing, joining methods (analytical and experimental), and design of lightweight structures. Dr. El-Zein has been with the John Deere Technology Center, where he currently leads a global materials and mechanics team, for 30 years.
