Abstract:The subject of this work is evaluation of the damage tolerance of double-lap, three-column and three-row composite bolted joints containing single missing fastener. Missing fastener is one of the damage scenarios may appear in manufacturing and service and it can cause reductions to the strength of the whole joint structure. A high-efficient explicit finite element model validated effective and accurate by experiments was developed and employed to evaluate the residual strength of multi-row composite bolted joints with single missing fastener. It is shown that the removal of fasteners can cause considerable reductions in joint stiffness, initial significant failure loads and ultimate loads of joints, and lead to a notable growth in bolt-load of bolts in the same column as or in the adjacent column to the missing fastener. © 2017 International Committee on Composite Materials.
