Abstract: Small oscillations of an elastic system of point masses (particles) with a nonlocal interaction are considered. The asymptotic behavior of the system is studied when a number of particles tend to infinity and the distances between them and the forces of interaction tend to zero. The first term of the asymptotic is described by the homogenized system of equations, which is a nonlocal model of oscillations of elastic medium.

Key words and phrases: nonlocal elasticity, homogenization, integral model, Eringen model.
