Prof.Dr.-Ing.habil.Dr.h.c.mult. Holm Altenbach is a full professor of Engineering Mechanics at the Otto von Guericke University Magdeburg, Faculty of Mechanical Engineering, Institute of Materials, Technologies, and Mechanics. He has 45 years of experience in teaching and research in various fields of mechanics (material modelling, mechanical analysis of thin-walled structures, composite mechanics, general strength problems, generalized continuum models, etc.). Since 2022 he is retired. Prof. Vladimir I. Erofeev is director of the Mechanical Engineering Research Institute of the Russian Academy of Sciences and a professor of the Institute of Information Technologies, Mathematics and Mechanics of National Research Lobachevsky State University of Nizhny Novgorod. He is a well-known scientist and specialist in such areas as wave processes in continuous media, nonlinear mechanics, and physical acoustics. He was the scientific supervisor for two doctors of sciences and 30 candidates of sciences. Three gold medals of the Russian Academy of Sciences awarded the scientific results of young scientists, carried out under the scientific supervision of Prof. Erofeev. Professor Erofeev is a member of the Russian National Committee on Theoretical and Applied Mechanics, a member of the European Council for Mechanics (EUROMECH), a member of the board of the Russian Acoustic Society, and a member of the Russian Academy of Sciences Academic Council on Acoustics. He was one of the organizers of several all-Russian scientific conferences and participated in the organizing committees of the IUTAM symposium (1999, Sydney, Australia), the EUROMECH colloquia (2006, Delft, the viii Preface Netherlands; 2009, Paris, France, devoted to 100 years after the publication of the book of the Cosserat brothers), and the Russian–French–German trilateral seminars on generalized continua (2010, Wittenberg; 2015, Magdeburg, Germany).Prof. Dr. Pavlov Igor Sergeevich is the vice-director of the Mechanical Engineering Research Institute of the Russian Academy of Sciences, and a head of the Department “Mathematical Methods in Radiophysics” Faculty of Radiophysics of National Research Lobachevsky State University of Nizhny Novgorod, Russia. His scientific interests include structural modeling of advanced materials, nonlinear wave dynamics of microstructured solids, and acoustic testing of microstructured materials. He is a member of the Russian Acoustical Society and the Russian National Committee on Theoretical and Applied Mechanics.
