Today, adhesive pipe joints are widely used in marine engineering equipment such as platforms and pipe lines, because of the manifest advantages, such as lower stress concentration, uniform stress distribution, lighter weight, water tightness, corrosion-resistance and better fatigue properties. However, adhesive joints in riser pipes are the most vulnerable part where most failures occur, because singular stress fields exist at the extremes of the interface between the adhesive and the adherend. In order to prevent premature failure of the joint systems, a study of adhesive pipe joints under the actual sea environment loadings, including as external pressure, internal pressure, tension, torsion, bending, and combinations of these, should be conducted. In this reported study, stress distributions were analysed in terms of the first-order laminated theory, and it was found that numerical results were in a good agreement with the obtained results obtained from the finite element analysis. In the light of these results, the failure of adhesive joints in deep sea riser pipes was discussed based on stress distributions on the interfaces as defined by theoretical analysis and Finite Element Method. Moreover, the effects of material properties and joint dimensions on the strength of adhesive joints under different load cases were studied.

“…From the open literatures, it is seen that there are only a few studies reported for the tubular joint with comparison to the beam/plate-like joint, and the earlier theoretical analysis works were focused on the isotropic adherends. Recently, due to the broader and broader application of the composite piping system in various engineering fields, the composite pipe joint problem has attracted more and more attentions (Graves and Adams, 1981;Chon, 1982;Hipol, 1984;Hashim et al, 1998;Yang, 2000;Harte et al, 2003;Yang et al, 2002;Pugno and Carpinteri, 2003;Kim and Lee, 2004;Zou and Taheri, 2006;Lees, 2006;Cheng et al, , 2007Oh, 2007).

In order to improve the joint failure strength, an adhesively bonded smart composite pipe joint system has been developed by integrating electromechanical coupling piezoelectric layers with the connection coupler. It has been validated that the integrated piezoelectric ceramic layers can smartly reduce stress concentration in the adhesive layer bond-line under bending or axial tension loads. In this study, piezoelectric particle/fiber reinforced polymer composite was utilized to construct adhesively bonded smart composite pipe joint systems, in order to overcome the brittle characteristic of the piezoelectric ceramic layers and to facilitate joint construction. Since torsion is one of the dominating loading conditions in practice, the behavior of the newly developed smart pipe joint system subjected to torsion loading was investigated in-detail to evaluate the effect of the integrated piezoelectric reinforced polymer composite layer on the joint performance. Firstly, based on the first-order shear deformation theory, the fundamental equations with relevant boundary and continuity conditions were developed to theoretically model the smart pipe joint system subjected to torsion loading. Further, the analytical solutions for the mid-plane displacements and the shear and peel stresses in the adhesive layer were obtained by using the Levy solution and the state-space method. Finally, some numerical examples were presented to evaluate the detailed effect of the stacking sequence and thickness of the integrated composite piezoelectric layers in the connection coupler on reducing the stress concentration in the adhesive layer; the effect of the applied electric fields on shear and peel stresses in the adhesive layer was also illustrated.

Structural adhesives are gaining wide recognition by industry as they offer engineering designers greater flexibility to achieve economic and technical advantages. In the marine industry there are potential applications for adhesives in various types of construction, for example, thick steel and composite adherends, (typically 5À15 mm thick). The applications include panels and large pipes. This article is largely concerned with the use of two-part epoxy adhesives. The purpose of this article is to understand and evaluate the weaknesses of adhesives and adherends, in relation to specific applications and to use design and material selection to alleviate them. This understanding can be extended to other thick adherend applications. This article will also highlight the impact of structural epoxy adhesive technology on the design and fabrication of steel, composite, and hybrid constructions. The benefits and inherent limitations that can accrue are quantified through three case studies related to thick adherend connections.
