**About the Editors**

**Ivan Galv˜ao** is an assistant professor at the Department of Mechanical Engineering of ISEL—Polytechnic Institute of Lisbon (Portugal) and an integrated researcher in CEMMPRE—University of Coimbra (Portugal). He completed a Ph.D. in Mechanical Engineering (Production Technology field) at the University of Coimbra. His research field includes the study of materials joining and processing, specifically welding technology and metallurgy, the mechanical behavior of welded joints, the solid-state welding of similar and dissimilar materials and the solid-state processing of materials. He has published many scientific papers in high impact journals and conference proceedings, and he has participated in several international conferences. He has also been involved in research projects, collaborated with international journals and engineering associations, as well as supervised research works and theses.

**Altino Loureiro** is a full professor at the Faculty of Sciences and Technology, University of Coimbra, Portugal. He has a Ph.D. in Mechanical Engineering, and an M.Sc. in Materials and Manufacturing Processes, Mechanical Engineering and Welding Engineering. He is the co-author of an internationally published technical book and of more than one hundred and twenty (120) articles published in international scientific journals, with more than two thousand eight hundred (2800) citations and an h-index of 31, according to the SCOPUS citation database. He has supervised or co-supervised ten (10) doctoral theses and more than sixty (60) master's theses.

**Ricardo Mendes** was born in Tomar (Portugal) in 1967. He is an assistant professor at the Faculty of Sciences and Technology, University of Coimbra, Portugal. He graduated in Physics Engineering and obtained his Ph.D. in Mechanical Engineering. His main scientific activity is within the area of high-pressure, high-temperature ultra-fast phenomena associated with the detonation physics of ideal and non-ideal explosives. Recently, he has also worked on the shock wave processing of materials like the detonation synthesis of nanopowders and explosion welding of metals. He is also involved in research projects and has published many scientific papers in high impact journals. He has participated in several international conferences, and supervised or co-supervised four (4) Ph.D. theses and more than fifty (50+) master's theses.
