In the context of increasing use of adhesive bonding for mechanical assembly, there is a need for reliable design tools. Both energetic and stress based conditions are necessary to predict the strength of bonded joints, which explains the use of a coupled criterion. The application of the criteria was performed by using Finite Element Analysis. Results obtained numerically were compared to experimental data from tubular bonded samples. A modification of the coupled criterion was proposed to take into account the loading rate in the prediction of the failure load. A good agreement was obtained between experimental and numerical predictions.
