“…In order to characterise the triaxialty and design an experimental specimen, several types of joint have been examined using FEA [23]. A butt joint under only tension, only torsion or a combination of tension and torsion loading is modelled.…”

“…The second type of joint that has been examined is cleavage joint, which shows mixed stresses even if it is only subjected to tension load [23]. Finite element analysis was performed to a cleavage joint under tension load of 1000 N. FE mesh of a cleavage joint is illustrated in Fig.…”

This paper summarises the research carried out to develop Finite Element (FE) modelling and predictive techniques for damage, fracture, fatigue and fretting fatigue problems. A damage model is developed based on Continuum Damage Mechanics and integrated within FE code. It is then used to predict the number of cycles to crack initiation in adhesively bonded joints. Furthermore, crack propagation algorithm is programmed within FE code using the principles of Fracture Mechanics and Paris law. The effect of mode mixity on crack propagation is taken into account using a Double Cantilever Beam (DCB) test specimen. Moreover, FE model of fretting fatigue aluminium test specimen is carried out in order to study the stress distribution and predict the crack propagation fatigue lifetime. Fretting fatigue problems involve two types of analyses; namely contact mechanics analysis and damage/fracture mechanics analysis. Both analyses are performed in FE code and the stress distribution along the contact surface between the two bodies is obtained and analysed. Furthermore, crack propagation analysis under fretting fatigue condition is presented. In most cases, the numerical results are compared to experimental ones.

“…Indeed, it does not necessitate a specific experimental apparatus and could be used with a classical tensile machine. By adjusting the bond-line angle of the adhesive, different tensile-shear loadings can be obtained [10] [11]. However, high stress concentrations are generated near the edges of the specimen [ [11][12] [13]] and the stresses are maximum at the interface [13] [11].…”

“…By adjusting the bond-line angle of the adhesive, different tensile-shear loadings can be obtained [10] [11]. However, high stress concentrations are generated near the edges of the specimen [ [11][12] [13]] and the stresses are maximum at the interface [13] [11]. It has also been recently shown that, using 2D [13] or 3D [12] Finite Element calculation, that an optimal angle leading to no edge effects could be determined.…”
