ABSTRACT	ESDU 91008 provides data to determine the minimum load to cause failure by rupture or by unacceptable permanent deformation of parallel-sided or tapered lugs with round or square ends under axial, transverse or oblique loading. The consideration of the effects of pin bending in a double shear joint is also included. The data on axial failure apply to any metallic material but those for transverse failure are for aluminium alloy or steel only. The data include empirical factors that are geometry dependent and are presented as curves. However, for axial loading the semi-empirical factor is both material and geometry dependent. The theory on which its calculation is based is outlined. A Fortran program, ESDUpac A9108, is provided on disc (uncompiled) in the software volume to determine it. The program requires input of the material characteristics and an elastic stress concentration factor that may be found from ESDU 81006. A complete lug strength analysis calculation is included to illustrate the use of the program and data.
