Large free-edge interfacial stresses induced in adhesively bonded joints (ABJs) are responsible for the commonly observed debonding failure in ABJs. Accurate and efficient stress analysis of ABJs is important to the design, structural optimization, and failure analysis of ABJs subjected to external mechanical and thermomechanical loads. This paper generalizes the high-efficiency semi-analytic stress-function variational methods developed by the authors for accurate free-edge interfacial stress analysis of ABJs of various geometrical configurations. Numerical results of the interfacial stresses of two types of common ABJs, i.e., adhesively bonded single-lap joints and adhesively single-sided joints, are demonstrated by using the present method, which are further validated by finite element analysis (FEA). The numerical procedure formulated in this study indicates that the present semi-analytic stress-function variational method can be conveniently implemented for accurate free-edge interfacial stress analysis of various type of ABJs by only slightly modifying the force boundary conditions. This method is applicable for strength analysis and structural design of broad ABJs made of multi-materials such as composite laminates, smart materials, etc.

Abstract The stress and strain distributions in adhesively bonded lap joints of hollow shafts with dissimilar materials subjected to torsional moments are examined using an axisymmetric theory of elasticity. In the analysis, the joint is modelled as an elastic three-body contact problem, and the hollow shafts, and the adhesive are respectively replaced by finite hollow cylinders. In the numerical calculations, the effects of the ratio of Young’s modulus of the adhesive to that of the shaft, the overlap length, and the thickness of the adhesive on the stress distributions at the interfaces in the joint are clarified. It is shown that the shear stress becomes singular at the ends of the interfaces between the shafts, and the adhesive, and increases near the ends of the interfaces with a decrease of Young’s modulus of the shaft, and of the thickness of the adhesive. For verification of the stress analysis, the strain distribution at an outer surface of an adhesively bonded lap joint was measured and a fairly good agreement was shown by comparing the experimental result with the analytical one.
