An expression for the Helmholtz energy of a metal has been derived using the embedded-atom method (EAM) within the classical perturbation theory. An expression for the effective three-particle distribution function with effective three-particle interactions taken into account within classical statistical thermodynamics has been proposed. Temperature dependences of the atomic density and the internal energy have been calculated for copper and gold. These dependences have been used to analyze the effective EAM-derived potentials.
