摘要：

The secondary bending phenomenon, which largely affects the state of stress and fatigue life of lap joints used in aircraft structures, has been investigated analytically, numerically and experimentally. In the first case a neutral line model, originally proposed by Schijve to estimate secondary bending moments induced in mechanically fastened joints with eccentricities has been used. Numerical FEM analysis involved riveting process and then the loading of the join with consideration of non-linear material characteristics and frictional contact conditions between joint elements. The results of the above theoretical analyses were compared with each other and validated based on the experimental tests that involved the strain gauge measurements of the joint and measurements of its deformations provided by digital image correlation technique. All analyses were carried out for riveted lap joints typical for aircraft fuselage structures, consisting of 2024-T3 Alclad aluminium alloy sheets connected with MS20470-AD universal head rivets.
