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. 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.) and in 1993 and was awarded the title of Professor in 2001. His main achievements are in the field of solid mechanics: wave and vibration processes in elastic and electroelastic bodies, numerical analysis of stationary deformation of anisotropic inhomogeneous shells and elastic bodies, and dentistry biomechanics.
