“…It is believed that, although the pins carry some load whilst the bondline is intact (unlike a bonded bolted joint [28]), the magnitude is much more significant once the bondline is damaged. As the interface disbonds, the load redistributes to the outer pin rows which subsequently deform.…”

a b s t r a c tA novel metal-composite joining technology is presented. Hybrid penetrative reinforcement (HYPER) uses small pins, protruding from the metallic part, to form an integrated assembly with high toughness. Different pin geometries and surface treatments are mechanically tested and compared. An ultrasonic, non-destructive inspection method is used to determine the failure modes. It is shown that the pins delay the initiation of failure, slow the propagation of damage and increase the ultimate strength by 6.5 times compared to an unpinned benchmark joint. The mean elongation at maximum load can be increased by over 400% and the energy absorbed can be more than 80 times higher, with reinforcement. Surface ''nano-structuring'' is also found to improve titanium-composite adhesion strength and consistency. Subsequently, a 25% higher load is required to initiate failure.

“…The simplified linear elastic method, originally presented in [12,13], is inspired by the FE method and allows for the resolution of the set of governing differential equations. The displacements and forces in the adherends, as well as the adhesive stresses are then computed.…”

“…Only simple manipulations on the stiffness matrix of the structure are required. An approach for the simulation of hybrid (bolted/bonded) joints can consist in employing macro-elements for the bonded parts and springs for the fasteners [12,13]. Finally, various mechanical or thermal loadings could be taken into account, through the vector of nodal forces.…”

“…Overview of the paper The mechanical and geometrical parameters are free; in particular, unbalanced configurations can be addressed. In the 1D-bar (1D-beam) frame, the adherends are simulated as linear elastic bars (as laminated linear elastic Euler-Bernoulli beams), while the adhesive layer simulation consists in continuously distributed linear or non-linear shear springs (in continuously distributed linear or non-linear shear and peeling springs).The adhesive layer thickness is assumed constant along the overlap.BBa and BBe elements were previously developed [12,13,15]. Nevertheless, they do not take into account the shear stress in the adherends.…”

International audienceThe Finite Element (FE) method could be able to address the stress analysis of bonded joints. Nevertheless, analyses based on FE models are mainly computationally cost expensive and it would be profitable to develop simplified approaches, enabling extensive parametric studies. Firstly, a one-dimensional 1D-bar and 1D-beam simplified models for the bonded joint stress analysis, assuming a linear elastic adhesive material, are presented. These models derive from an approach, inspired by the FE method using a formulation based on a four-node macro-element, which is able to simulate an entire bonded overlap. Moreover, a linear shear stress variation in the adherend thickness is included in the formulation. Secondly, a numerical procedure is then presented to introduce into both models an elasto-plastic adhesive material behavior, while keeping the previous linear elastic formulation. Finally, assuming an elastic perfectly plastic adhesive material behavior, the results produced by simplified models are compared with the results predicted by FE using 1Dbar, plane stress, and three-dimensional (3D) models. Good agreements are shown

In this paper, the effects of bolt torque tightening on the fatigue strength of double‐lap simple bolted and hybrid (bolted/bonded) joints have been studied experimentally. To do so, two types of joints, that is, double‐lap simple and hybrid (bolted/bonded) joints, were studied. For each type of joints, three sets of specimens were prepared and subjected to the tightening torque of 1, 2.5 and 5 Nm, and then, fatigue tests were carried out at different cyclic longitudinal load levels. Experimental tests results showed that the hybrid joints have better fatigue performance in comparison with the simple bolted joints. In addition, the investigation revealed the positive role of tightening torque on the fatigue life of both simple and hybrid joints.
