Abstract (EN): Adhesive joints are extensively used for structural joining in diverse industrial sectors. However, unlike other types of joints, adhesive joints experience a wide range of damaging loadings and environmental conditions during service, which can have a major impact on joint performance. Precise stress analysis is thus essential to help the designer to guarantee that the mechanical performance of the joints will meet performance targets during the service life. Consequentially, several approaches have been proposed to analyse the stress state along the bondline in an adhesive joint. Analytical models and the finite element methods (FEMs) are the most important tools available for joint designers. Analytical approaches are simple, highly suitable for parametric analysis, and can be calculated quickly. However, such models are based on several assumptions and simplifications that might limit the quality of the results. These models are also limited to a small number of joint configurations and relatively simple material behaviours. In contrast, the FEM is much more flexible and is preferable for the design of geometrically complex joints. In this chapter, different stress analysis approaches appropriate for designing bonded joints have been reviewed. Analytical models for several typical joint geometries have been discussed and FEMs suitable for different material behaviours have been explained. It is also shown that despite the extensive available literature on the stress analysis of adhesive joints, there is still ample room for further research.
