Secondary bending in multi fastener, composite-to-aluminium single shear lap joints

Effect of secondary bending on strength prediction of composite, single shear lap joints

“…A stress singularity is also introduced when the bolt is tilted in its hole as the surface contact changes into a line contact. Experimental investigations of single shear lap joints in which the influence of geometry [7,25,30,32], stacking sequence [7,25,27,30], clearance [27], clamping force [27,30,32], fastener type [27,30,32], lateral support [30] and stiffness mismatch between member plates [32] have been conducted. Several numerical studies have also been conducted where the effect of the above parameters were investigated [3,[21][22][23]29,32,33].…”

An experimental investigation on the bearing failure load of glass fibre/epoxy laminates

“…It is worth taking into account the results obtained by Hassan et al [3], Camanho and Matthews [4], Kelly and Hallström [5], Li et al [6], Lie et al [7], Ekh et al [8], Ekh and Schön [9], Vangrimde and Boukhili [10,11], Xiao and Ishikawa [12], Ireman [13], Yanet al [14], Starikov and Schön [15].…”

A global bolted joint model for finite element analysis of load distributions in multi-bolt composite joints

“…Such analysis methods are capable of analysing realistic scenarios including clearance and bolt-torque [1][2][3], friction between member plates [4], load distribution in multi-bolt joints [5,6] and material damage [7][8][9]. Secondary bending, which is caused by an eccentric load path in single-shear joints, is also captured by such detailed models [3,10]. However, these methods have generally used three-dimensional solid finite elements, which are prohibitively expensive for large-scale structural analysis where hundreds of bolts can be present [2].…”
