✦ Synopsis
The general expression for the energy dissipated by Coulomb friction in layered beams, valid for any number of layers and for any slipping level, is derived. The expression of optimum pressure for maximum energy dissipation is also derived. It is shown, in particular, that this optimum pressure does not guarantee minimum vibration amplitude at resonance if the beam is excited by a harmonic force. The results obtained, concerning the energy dissipated and the optimum pressure, are adapted to the case of leaf springs, for which the concept of optimum pressure seems to be more meaningful.
