12 Data Tabulations

The following tables present summaries of the results of many of the finite element calculations described in this book. The model numbers refer to the joint configurations and fastener types (see Introduction for code keys and definitions of computational models). Details of each model number may be found in the tables in Appendix A. The finite element models used to obtain these data are described in detail in Chapter 13; the material properties for the various models are described in Chapter 15.
The effects of rivet geometry (countersinking), rivet material and interfacial friction coefficient are included. Interference and lateral clamping are not treated. Load transfer through the joint, the joint compliance, rivet tilt, the local slips at rivet-panel and panel-panel interfaces, contact pressures and local stresses are presented.
The excess compliance is defined as C = C′ − C″ . C′, the assembly compliance, is the ratio of the net extension, δ, to the load per repeat distance, P. C″ is the compliance of a continuous panel having the same length, L, as the model joint (length of two panels minus the overlap) and the same cross sectional area, A, and elastic modulus, E, as a single panel. The excess compliance is related to the displacement, bending and deformation around the rivet.
