Abstract

In the recent years, a coupled energy and stress approach has been used successfully to treat problems involving stress concentration since the stress-based criteria only are no more valid near a singularity. For the adhesive failure characterization, Roche et al. [4] have developed a 3-point bending test which has a similar stress concentration condition, and thus the coupled criterion can be applied to predict the failure of the adhesively bonded joint. For mechanical properties determination, the semi-analytical approach Macro-element technique is used, and the results will be compared with Cohesive Zone Model (CZM) based on damage mechanics.
