Carpóforo Vallellano (Foro) received his PhD in Mechanical Engineering from the University of Seville (Spain) in 1999, where he is currently a Professor of Manufacturing Process Engineering in the Department of Mechanical and Manufacturing Engineering. With over 30 years of teaching experience and more than 25 years of research activity, his work focuses on metal forming, manufacturing engineering, and material failure, particularly fatigue and fracture.

He has led numerous competitive research projects and industrial collaborations, notably with Airbus, and has served as Principal Investigator in multiple initiatives. He is the co-author of more than 140 scientific publications and a member of the European Structural Integrity Society (ESIS), the Spanish Group of Fracture (GEF), and a founding member of the Spanish Manufacturing Engineering Society (SIF).

He has conducted research and teaching stays at leading institutions, including the Department of Engineering Science at the University of Oxford (UK), the Department of Mechanical Engineering at the University of Sheffield (UK), and the Graduate Aeronautical Laboratories at the California Institute of Technology (Caltech, USA). In addition, he has performed key academic and research evaluation roles at both national and international levels.

He currently coordinates the Master’s Degree in Aeronautical Industry Operations in collaboration with Airbus Defence and Space (Spain) and serves as Head of the Department of Mechanical and Manufacturing Engineering at the University of Seville.

Hui Long is Professor of Mechanics of Materials in the School of Mechanical, Aerospace and Civil Engineering, the University of Sheffield, United Kingdom. Her research interests are centred around flexible sheet forming technologies, including Incremental Sheet Forming (ISF) and Spinning. She led two recent UK EPSRC Adventurous Manufacturing projects (EP/T005254/1 and EP/W010089/1) in developing novel ISF tooling and new Rotational Vibration assisted ISF (RV-ISF) for hard-to-form Mg and Al alloys. Her team developed two new material test methods, tension under cyclic bending and compression (TCBC) and biaxial tension under bending and compression (BTBC), to investigate the enhanced material formability due to multi‐axial and cyclic loading in ISF. In Sheet Metal Spinning, her team developed advanced modelling techniques for wrinkling simulation and testing methods leading to new understanding of wrinkling mechanisms and development of wrinkling-free processing maps. She is a Chartered Engineer and Fellow of the Institute of Mechanical Engineers (IMechE, UK). She is an Associate Editor of IMechE Part B Journal of Engineering Manufacture and ASME Journal of Tribology.
