Professor Viacheslav L. Bogdanov was born on November 25, 1965, in Kyiv Region of Ukraine and graduated from the Faculty of Mechanics and Mathematics of Kyiv State University in1989. He is working at the S. P. Timoshenko Institute of Mechanics of the National Academy of Sciences of Ukraine (NASU) since 1989, receiving an appointment as Principal Researcher (2009). He is serving as Vice-President of the NASU and Head of Section of Physical, Technical and Mathematical Sciences of the NASU (from 2020 until present). He received the Candidate of Sciences degree (Ph.D.) (1992) and the Doctor of Sciences degree (2009) in Physics & Mathematics. He is Academician of the NASU (since 2015). His principal scientific results have been obtained in the mechanics of deformable solids: fracture mechanics, the three-dimensional theory of stability of deformable bodies, and mechanics of composite materials. He developed a combined approach to investigating non-classical problems of fracture mechanics (problems of fracture of pre-stressed bodies with cracks and fracture of solids under compressive loading along parallel cracks). He is Author or Co-author of 18 monographs, textbooks, reference publications, and more than 150 scientific papers.
Prof. Volodymyr M. Nazarenko was born on 19.03.1956 in Oryol (Russia). He graduated from Kyiv University in 1978 and works at the Institute of Mechanics of NAS of Ukraine. Since 2012, he serves as Head of the Department. His scientific work is in the field of mechanics of deformable solids, mechanics of fracture of materials, and related areas: non-classical problems of fracture of materials in compression along cracks and under the action of initial stresses along cracks and problems of loss of stability of deformable bodies.
Professor Roman M. Kushnir is Chief of Department of Thermomechanics and Director of the Pidstryhach Institute for Applied Problems of Mechanics and Mathematics of Ukrainian National Academyof Sciences, L'viv, Ukraine. He was graduated from Technical University "L'vivska Polytechnic Institute" in 1976 and obtained the Ph.D. (Physics & Mathematics, Mechanics of Solids) from Institute for Applied Problems of Mechanics and Mathematics of Ukrainian Academy of Sciences in 1981, L'viv, Ukraine. In 2000, he got the D.Sc. degree (Physics & Mathematics, Mechanics of Solids) from the Pidstryhach Institute for Applied Problems of Mechanics and Mathematics of Ukrainian National Academy of Sciences. He supervised seven Ph.D. theses and three D.Sc. theses and acted as Author/Co-author of 4 books and 300 journal and conference papers. His research interests are determination and investigation of stressed-strained state and limit equilibrium of piecewise-homogeneous bodies with thermal and residual strains and structural imperfections (inclusions and cracks) using the distribution technique, formulation of direct and inverse mechanics problems, and development of methods for their solving, in particular, for the thermosensitive bodies and the composite shells.
Prof. Dr. Alexander Ya. Grigorenko was born in Kyiv on June 17, 1955. He was graduated from the cybernetics department at the Kyiv State University in 1977 with a Diploma in Applied Mathematics, has worked at the Institute of Mechanics since 1981, and has headed the department of numerical methods since 2005. He defended Ph.D. thesis in 1980 and Dr. Sci. thesis Phys.-Math. in 1993 and was awarded the title of Professor in 2001. He is Academician of the NASU. His main achievements are in the field of solid mechanics: wave and vibration processes in elastic and electro-elastic bodies, numerical analysis of stationary deformation of anisotropic inhomogeneous shells and elastic bodies, and dentistry biomechanics.
Mikhailo Selivanov was born on July 29, 1973, in Kyiv, Ukraine. He studied at the Faculty of Mechanics and Mathematics at Taras Shevchenko National University of Kyiv from 1990 to 1996. From 1996 to 1999, he pursued postgraduate studies at the S.P. Timoshenko Institute of Mechanics of the National Academy of Sciences of Ukraine (NASU). In 2003, he defended his Ph.D. dissertation in physics and mathematics. Since 2003, Dr. Selivanov has held various research positions at the S.P. Timoshenko Institute of Mechanics, progressing from junior researcher to leading researcher. He was awarded the academic title of Senior Research Fellow in 2007. In 2017, he defended his doctoral dissertation in physics and mathematics. Since 2023, he has served as Deputy Director of the S.P. Timoshenko Institute of Mechanics of NASU. In the same year, he was elected Scientific Secretary of the National Committee of Ukraine on Theoretical and Applied Mechanics. His research interests include fracture mechanics and the mechanics of viscoelastic materials, with a focus on the slow propagation of cracks. He is the author or co-author of approximately 100 scientific publications.
