    Abstract:
    Dry friction damping due to axial sliding surfaces normal to the principal lateral direction of structural motion is studied. Primary emphasis is on sufficiently large motion that slipping occurs throughout a cycle. Beams with arbitrary support conditions and vibrating in an arbitrary mode are considered; also a pinned-pinned rectangular plate is studied. In all cases, a simple explicit formula is obtained for an equivalent, linear, viscous critical damping ratio
