Abstract
The paper presents the results of experimental research and finite element analyses (FEA) on the impact of the aircraft rivet installation process and the type of rivet material on the geometric parameters of the driven rivet head, rivet hole expansion (relative interference), residual stresses in sheets, clamping stress and clamping force between sheets in three-row riveted lap joints, as well as linking the obtained results with observations of fatigue crack initiation sites in real riveted joints. The research was conducted for universal head rivets (MS20470AD5-5 and MS20615-5M5) with a shank diameter of 3.96 mm and a length of 7.94 mm, made of two materials, namely aluminium alloy (2117-T4) and nickel-copper alloy (Monel 400), used to join two AA2024-T3 sheets with a thickness of 1.0 mm and 1.6 mm. The experimental tests focused on determining the mechanical properties of sheet and rivet materials (using the digital image correlation DIC technique), geometric parameters of driven rivet heads, and rivet hole expansion, depending on the rivet material and the riveting force level. The results obtained from the numerical models revealed that at the same degree of rivet squeezing, rivets made of Monel 400 generate significantly higher negative residual stresses and residual clamping than rivets made of AA2117-T4, which will affect the contribution of friction to load transfer by a given rivet row and the fretting phenomenon in real riveted joints. The region of compressive residual hoop stress in sheets and the clamping force influence the fatigue crack initiation site and the crack path.
