Abstract A good understanding of the process of adhesion from the mechanics viewpoint and the predictive capability for structural failures associated with adhesively bonded joints require a realistic modeling (both constitutive and kinematic) of the constituent materials. The present investigation deals with the development of an Updated Lagrangian formulation and the associated finite element analysis of adhesively bonded joints. The formulation accounts for the geometric nonlinearity of the adherends and the nonlinear viscoelastic behavior of the adhesive. Sample numerical problems are presented to show the stress and strain distributions in bonded joints.

Major Factors

Adhesive bonding is a high-speed fastening method which is suitable for joining advanced lightweight sheet materials that are hard to weld. Latest literature relating to finite element analysis (FEA) of fatigue behaviour of adhesively bonded joints is reviewed in this paper. The recent development in FEA of fatigue behaviour of adhesively bonded joints is described with particular reference to three major factors that influence the fatigue behaviour of adhesively bonded joints: failure mechanism, environmental effects and hybrid joining techniques. The main FE methods used in FEA of fatigue behaviour of adhesively bonded joints are discussed and illustrated with brief case studies from the literature.

Analysis Methods

Adhesive bonding is one of the effective ways to reduce the weight of structures. Researchers have done lots of numerical analysis and finite element analysis taking into account of the complex stress state in the bonded area, as well as the stress singularity occurs at the overlap edges with a view to efficiently predict the strength and rigidity of adhesively bonded joints. As they may suffer shock or impact loads in practice which leads to high strain rate in structures, analysis methods for adhesively bonded joints differ from that at quasi-static condition for two reasons: one is the mechanical properties of materials, including adhesives and substrates are different at high strain rates, the other is the additional consideration of elastic wave propagation in solid body. This article summaries several finite element analysis methods for adhesively bonded joints at high strain rate developed by domestic and foreign scholars and corresponding experimental standards for determining required parameters of each analytical method and raised some questions that need for further study.
