A simple analytic embedded-atom model that includes more than nearest neighbors is presented. Parameters for Cu, Ag, Au, Ni, Pd, and Pt have been obtained. The model has been applied to study the thermodynamic properties of copper with molecular dynamics. The calculated fractional density change on melting, heat of fusion, linear coefficients of thermal expansion, and heat capacities above room temperature are in good agreement with experimental results.
