The role of a fastener is to transfer the load from one sheet to another sheet in the overlap region. For a configuration with more than one row of fasteners, the applied force P is split at the first row into the bypass load (T BP), which remains in the sheet, and the transfer load (T TR) transmitted to the other sheet, as schematically shown in Fig. 5.1. The T TR-load is comprised of a bearing force (T BR) resulting from the bearing pressure exerted by the rivet shank on the hole surface and a friction force (T FR) induced by friction between the mating sheets. Friction is localized mainly beneath the rivet heads where maximum clamping occurs. Works reviewed in the present chapter reveal that, for well-tightened fasteners, frictional forces can transmit a significant portion of the transfer load.
