Aim of work - development of the theoretical and numerical models for the description of the behavior of nanostructured materials under external influence. Description of the dynamical processes that occur in the samples at deformations of a different type and at melting within developed models. Calculation of the mechanical and structural parameters of metallic nanoparticles and nanostructured ternary compounds. Methods of investigations - methods of classical molecular dynamics with the embedded atom model and three-body interatomic potentials, methods of nonequilibrium thermodynamics and elastic theory, methods of computational mathematics etc. Numerical model that describes the behavior of the nanostructured materials under external influence is build. Computer algorithms for parallel calculations that simulate different types of deformation and melting processes of the samples are developed. The scheme for calculation of the mechanical parameters, namely elastic constant and shear modulus for nanosized systems also developed. Within developed models process of melting of metallic nanoparticle is investigated. Corresponded dependencies and atomistic configurations of the samples under investigation are calculated.
