“…Convergence property is a major problem in composite structure damage simulation model, and generally, it is affected by the factors such as moduli of materials, contact conditions and algorithm [24]. Improving convergence property can not only save computing time but also provide the results of structure damage and failure process, which is of great significance to investigate the damage and failure mechanism of structures.…”

A 3D progressive model with better convergence property is established to capture the mechanical properties and damage mechanism of a composite bolted π-joint under bending load and shown to closely match experimental results. This model is then used to investigate the effect of internal laminate stacking sequence and surface layers thickness on the bending performance of the joint. It was found that the stacking sequence and the surface layers thickness have a significant effect on the matrix crack and delamination distributions in the joint, respectively. Local surface layer thickness can be designed to control the delamination damage around the bolt hole. Finally, volume fraction of 0° layer in the internal laminate and surface layer thickness are used to improve the joint bending performances by proper design.

“…The washers, nut, and bolt shank were integrated as one part as in McCarthy et al. 10 The laminates were discretized by eight-node reduced integration continuum shell elements (SC8R), 25,26 where only one element was used in the thickness to include all the plies (since the laminates are relative thin) and thus largely reduce the cost of analysis. Three integration points were used in the thickness direction of every layer of the composite section.…”

This paper presents a numerical investigation into the effects of missing fasteners on the mechanical characteristics of double-lap, multi-row composite bolted joints. A highly efficient explicit finite element model, which was validated effective and accurate by experiments, was developed and employed to conduct the virtual tests. Single-column and multi-column joints with various positions of missing fastener were considered. It is shown that the removal of fasteners can reduce the joint stiffness significantly, especially in joints with fewer columns or missing fasteners in the outside rows. The removal of fasteners can also cause considerable reductions in both the initial significant failure loads and ultimate loads of multi-column joints, while in single-column joints only the initial significant failure loads are influenced. Considering the load distribution, it is suggested that bolts in the same column as or in the adjacent column to the missing fastener experience a notable growth in load. Meanwhile, if a bolt bears more loads in the pristine joint, the larger changes in stiffness, ultimate strength, and load distribution may be obtained when it is lost.
