About the Editor and Authors
Prof. Dr. rer. nat. Dr. h. c. Siegfried Schmauder (Author)
Prof. Schmauder was educated in Stuttgart/Germany where he received his Diploma in Mathematics in 1981 at the University and where he finished his PhD in Materials Science in 1988 at the Max-Planck-Institute for Metals Research. Prof. Schmauder then did Postdocs at the University of Tokyo from 1989-1990 and at the University of California at Santa Barbara (UCSB) from 1990-1991.
He returned back to Stuttgart where he became a group leader in Structural Mechanics at the Max-Planck-Institute from 1991-1994. He was nominated as full Professor for Strength of Materials and Materials Techniques in the Faculty of Mechanical Engineering at the University of Stuttgart in 1994.
He has published 6 books and more than 600 scientific papers.
Since 1991 he is the organizer of the annual international workshop on Computational Mechanics of Materials. For more than 10 years he was co-editor of the Journal Computational Materials Science (CMS). His main research field is multiscale materials modelling from atoms to components.
He is a guest professor in Tomsk (Russia) and Tokyo (Japan) and in 2017 he received an honorary doctorate from the Ovidius University in Constanca/Romania for his achievements in multiscale materials modelling.
Kiarash J. Dogahe, M.Sc. (Editor)
Kiarash Dogahe was born in 1993 in Rasht, Iran. He studied Materials Engineering and Nanotechnology at Politecnico di Milano, Italy. Since 2020 he has started to work as a scientific co-worker at the Institute for Materials Testing, Materials Science and Strength of Materials (IMWF), University of Stuttgart, Germany. The main area of his work is the investigation of fatigue behavior of metallic components produced by Additive Manufacturing methods.
Dr. Marijo Mlikota (Author)
Dr. Marijo Mlikota is a simulation engineer at the company Magna Steyr Fahrzeugtechnik AG & Co KG in Graz, Austria, where he is a part of the Aerospace department. He was born in Konjic, Bosnia and Herzegovina, in 1986. He obtained his M.Sc. degree in mechanical engineering, with specification in computer aided engineering, in 2010 at the Faculty of Mechanical Engineering and Naval Architecture, University of Zagreb, Croatia. From 2011 until 2021 he worked as a scientific co-worker at the Institute for Materials Testing, Materials Science and Strength of Materials (IMWF), University of Stuttgart, Germany. He obtained his doctoral degree there in 2020, too. Aside of fatigue of metallic materials, he was involved in the research field of metal erosion and soft tissue behavior.
Prof. dr. sc. Željko Božić (Author)
Prof. Željko Božić is a Full Professor at the Faculty of Mechanical Engineering and Naval Architecture, University of Zagreb, where he is the Head of the Department of Aeronautical Engineering. He achieved a Dipl. Ing. degree in mechanical engineering in 1987 and a M.Sc. degree in structural mechanics in 1992 at the Faculty of Mechanical Engineering and Naval Architecture, University of Zagreb.
In 1993 he was awarded the Japanese Government (Monbusho) Scholarship for his PhD study in the Department of Naval Architecture and Ocean Engineering at Yokohama National University in Japan, where he received his PhD in the Fatigue and Fracture of Ship Structures, in 1997. He was awarded the Silver Medal of Yokohama National University. From 2001 to 2004 he worked in R&D Department in ALSTOM Power, Baden, Switzerland, on fatigue and integrity of gas turbine structures. He was a DFG (German Science Foundation) guest professor at the University of Stuttgart in 2010, 2011, 2012 and 2014. He was a visiting professor at University of Bergamo, Italy, in 2018 and 2021.
His research interests include analytical, numerical and experimental methods to treat fatigue and fracture of structures. In particular, modelling and analysis of fatigue crack propagation considering residual stress effects and interaction of multiple cracks. He is the European Structural Integrity Society (ESIS) Executive Committee (ExCo) member and he was the Organizing Committee Chair of the 4th ESIS Summer School, held in Dubrovnik in 2017. He was the Organizer and Chair of several International Conferences including the International Conference on Structural Integrity and Durability (ICSID), which he initiated in 2017 and which is since then held every year in Dubrovnik. He was Guest Editor of Special Issues of the Engineering Failure Analysis journal, International Journal of Fatigue, Fatigue and Fracture of Engineering Materials and Structures, Procedia Structural Integrity, and other journals. He gave more than 70 oral presentations at conferences and workshops including five plenary lectures.
