Abstract

Adhesive bonding technology is widely applied in the assembly and repair processes of composite laminates. However, the debond flaws existing in the adhesive layer weakens the load-carrying capacity of adhesively bonded structures. This article presents an analytical model to investigate the adhesive shear behaviour of double-lap joints containing a debond flaw. Differential element method is employed to simulate the stress and strain distribution of adhesive layer, which considers anisotropy of each ply in the composite laminates and elastic-perfectly plastic behaviour of the adhesive. This model can compute the stress and stiffness of adhesive double-lap joints with different debond flaw conditions, covering fully debond ones as well as non-fully ones. Finite element model of double-lap joints is built in this paper to validate the accuracy of proposed analytical model. We also compared the debond flaw joints and non-flaw ones in terms of their adhesive strain and stress distribution.
