“…A finite element analysis was used to calculate the residual thermal stresses generated by cooling down from the adhesive cure temperature and a nonlinear analysis incorporating the nonlinear adhesive behavior was performed [9]. Taheri et al [10][11][12][13] developed a simple method for assessing the behavior of adhesively bonded tubular joints under torsion, based on a parametric study conducted by 2D and 3D finite element analysis. A finite difference method was utilized to solve the system of equilibrium equations and it was modeled as a separate 3D elastic body without the uniform stress assumption [14].…”

Bonded joints are very common in many pipeline systems, in which the bond behavior of the joint interface is of crucial importance. This paper presents two analytical solutions for the debonding process of a pipe joint under torsion, assuming that the bond interface follows either an exponential softening bond-slip law or a simplified bilinear model. The solutions are general, applicable to composites and metallic and indeed other pipes. Based on the analytical solutions, the influences of the bond length and stiffness on the torque-displacement curve and ultimate load are investigated. The solutions can be used to explain the stress transfer mechanism, the interface crack propagation, and the ductility of the joint.

The mechanic behavior and debonding process of pipe joints’ interface are the key points of pipe system. Load carrying capacity of pipe joints is the most important indicator that industry concerns. In this paper, results of finite element method (FEM) using ABAQUS modelling are given. Through parametric study, the load-displacement relationship, ultimate load and ductility of the joints can be explained. The thickness of adhesive layer is also taken into consideration.

“…His results proved that both the failure mode and joint strength were strongly dependent on the stacking sequence and adhesive thickness as well as on the adherend material. Taheri and his research group [5][6][7][8][9] conducted a series of investigations to characterize the response of adhesively bonded tubular joints mating composite/metal adherends under both static and cyclic torsion loadings. Their work studied the effect of various parameters such as the adhesive layer length and thickness, the adherends diameters, and the material properties of the adherends for characterizing the full behavior of such joints.…”

The use of composite materials has been extensively increasing in the recent decades, mainly due to their high strength and stiffness to weight ratios, as well as their non-corrosive attribute. Adhesive joints are used effectively to join composites to composites or to dissimilar materials. Components made of composites may contain some defects in the form of delaminations that may adversely affect their overall behavior and response when subjected to different loading systems. Interlaminar stresses (including out-of-plane stresses) are caused by the mismatch in material properties, especially in Poisson's ratio and the so-called 'coefficient of mutual influence' (between adjacent layers). The goal of this paper is to evaluate the interlaminar stresses that exist at the delamination fronts in a composite pipe, hosting a small delamination, adhesively bonded to an aluminum pipe. The aim is also to study the effect of various parameters (such as delamination length, depth, fiber orientation angles, and stacking sequence) that influence the performance, using the finite element method. The system is subjected to a torsional moment, which can be considered as a critical loading condition in tubular adhesive joints. Results of the study provide valuable information about the behavior of adhesive joints with delaminated composite adherends, and reveal the nature and distribution of interlaminar stresses along various delaminated fronts under torsional moments.
