Response of multiple fastener composite joints: numerical and experimental results
periments and predictions was found to be excellent around the net-section region. Although predictions for other strains were not as good, they were within the range of experimental data. Distribution of contact stresses between the pins and the hole edges was also studied. Numerical analysis …

Experimental and Numerical Study on Bolted/Bonded Composite Joints for Aircraft
Bolted and bonded joining technologies in composite structures have been widely studied since the 1970s. Although every technology has advantages and disadvantages, bonded joint technology has the potential to reduce the weight and manufacturing cost of advanced aircraft structures. However, bolted …

Effects of load proportioning on the capacity of multiple-hole composite joints
… is a maximum. Specifically two-hole-in-series joints are examined. The results indicate that when each hole reacts 50% of the total load, the joint capacity is not a maximum. One hole generally is understressed at joint failure. The algorithm developed to determine the load proportion at each …

Effects of Curing Cycle and Loading Rates on the Bearing Stress of Double Shear Composite Joints
… metal structures are being replaced by advanced composite structures. The major advantage of an advanced composite structure is the huge reduction in the number of parts and joints required. Also composite materials provide better resistance to creep, corrosion, and fatigue. However, one cannot …

Modelling and analysis of composite structures with semi-rigid connections
The composite structures studied in this thesis involve concrete slabs with profiled steel sheeting supported by steel beams. The composite interaction is realized by providing shear connectors welded to the top flange of the steel beams. The columns are normally noncomposite. The steel beam-to …

The behaviour of composite beam-to-column flush end plate connections using blind bolts
… scenarios. Two sub-assemblages of cruciform composite beam-to-column joints connected using blind bolts were tested under static and cyclic loading. The test results were used to obtain the load-displacement characteristics of the connection, failure modes and strain development. The test …
