The history of computer application in physics for solving nonlinear problems is considered. Examples from different
branches of condensed matter physics (nonlinear vibrations of anharmonic chains of atoms, dynamics of radiation damage
of crystals, deformation and fracture of crystals) are given. A new line of investigation and the results obtained in the
field of computer simulation of physical processes realized in the department of metal physics and computer technologies
in materials science are considered. This line incorporates both a study of self-organization and properties of new
materials (fullerenes, carbon nanotubes) and biological objects by molecular dynamics technique as well as the development
of new computer simulation methods.
