INFLUENCE OF NONLINEAR INTERACTIONS AND BOUNDARY EFFECTS ON THE PROPAGATION OF ENERGY IN A ONE-DIMENSIONAL PARTICLE CHAIN
V. S. Vikhrenko and S. V. Dubinin UDC 536.24.01 A one-dimensional system (chain) of particles interacting with each other and with the substrate has been investigated by the method of computer modeling. Particles at the boundaries of the chain, which are considered separately, represent self-oscillating systems. The influence of the parameters of a system on the transfer of energy by the chain has been studied; the behavior of the system in the transient and steady-state regimes of motion has been investigated. It has been shown that the stationary states of the system are characterized by a nonuniform distribution of the average particle velocities (temperatures) squared over the chain's length. A correlation between the increase in the thermal resistance of a system and the enhancement of its structurization has been established.
