Selected Problems of Solid Mechanics and Solving Methods (eBook)

This book examines new approaches for the estimation of errors in approximate theories. Numerical and analytical methods in mechanics often require the establishment of a set of basic equations, and various approaches exist to create approximate theories from them. The problem is that nobody knows the boundaries of the estimation of errors in approximate theories.

This book presents new approaches to overcome this problem and to provide the reader with suitable methods for the relevant field, including a representation of different scientific schools and different countries. These new methods are helping to solve many problems not only in analytical Mechanics but also in Physics, Mathematics, and Civil Engineering.

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.

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 politekhnika' 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.
