In the case of joints eccentric with respect to the load path, like lap joints or single strap butt joints, out-of-plane deformations of the sheets referred to as secondary bending (SB) occur under nominally tensile loading. Maximum moments due to SB are induced at load path eccentricities, namely at the rivet rows. As said earlier, for a lap joint with more than two rivet rows, the maximum bending moment is always induced at the outer rows. The out-of-plane deformation of a lap joint with three rivet rows associated with SB is shown in Fig. 6.1a. The largest tensile stresses due to SB are produced along the faying surface at location A of sheet 1 and location B of sheet 2. Because outside the outer rivet rows either sheet carries the full applied tensile load, A and B are also locations of the maximum combined tensile stresses and, therefore, the most commonly observed fatigue crack initiation sites.
