The monograph presents the latest advances in the field of analytical and computer simulation of mechanical processes in condensed matter with microstructure. Are discussed in detail as methods of computer modeling, and theoretical basis of the description of the processes of deformation and razrusheniya.Podhody discussed in the book, it is particularly important for the description of processes, in which there is discontinuity of the material, as well as the transition to large-scale levels, which is an essential consideration of atomic the structure of matter, in particular, to describe nanostruktur.Monografiya contains both the original results of the author, and the necessary training of character information from the relevant mehaniki.Kniga sections based on articles published by the author in recent years in the Russian and foreign izdatelstvah.Dlya researchers, teachers, graduate students and university students studying the physical and mathematical specialties.
