Computational Models of Adhesively Bonded Joints
Simulations using the Finite Element Method (FEM) play an increasingly important role in the design process of joints and fasteners in the aerospace industry. In order to utilize the potential of such adhesive bonding, there is an increasing need for effective and accurate computational methods. The geometry and the nature of an adhesive joint are, however, not so simple to describe effectively...
متن کاملAnalytical Solution of Stress Field in Adhesively Bonded Composite Single-Lap Joints Under Mechanical Loadings
In this paper, considering an adhesively bonded composite single-lap joint, a novel approach is presented to predict the peel and shear stress distributions of the adhesive layer for an ASTM standard test sample. In current method, the equilibrium equations are derived using the energy method and based on the Timoshenko’s beam theory. Two solution procedures then are discussed, one of which rep...
متن کاملThe Effects of Pre-bond Moisture on the Fracture Behaviour of Adhesively-bonded Composite Joints
The results of an investigation into the effects of pre-bond moisture absorbed by fibrecomposite substrates prior to bonding with various structural epoxy adhesives are presented. Substrates were bonded in the as-received condition (where substrates had been exposed to atmospheric moisture for periods of greater than three months) and were also bonded in the fully-dried condition (after drying ...
متن کاملCrack Path Selection in Adhesively Bonded Joints: the Role of Material Properties
This paper investigates the role of material properties on crack path selection in adhesively bonded joints. First, a parametric study of directionally unstable crack propagation in adhesively bonded double cantilever beam specimens (DCB) is presented. The alternating crack trajectories in specimens of various material systems are simulated using the finite element method and the results indica...
متن کاملPropagation of ultrasonic Lamb waves in adhesively bonded lap joints
This paper considers the bonded joint as a multilayer structure that is analysed using the Transfer Matrix method. In this particular case three layers (two adherents and the adhesive) are considered. The study of this propagation problem may be developed from matrix formulations which describe elastic waves in layered media. This technique combines the theory of the dynamics of the continuum w...
