| The embedded atom method is adapted to study solid friction and the mechanical behavior of a model metal which incorporates the effect of electronic glue in its structure. The elastic properties of real metals are reproduced by a set of basic model potentials as revealed by analytic considerations. A slightly modified version of a classical NonEquilibrium Molecular Dynamics (NEMD) computer simulation is employed to study the dynamics and structural changes of the model metal undergoing a process of solid friction and an uniaxial compression, in order to analyze, e.g. plastic yield, transient friction coefficients, and the underlying structure. Under appropriate choice of parameters, the model turns out to be also applicable to study multiscale structures in porous metals.
