In this experimental study, the fatigue damage of glass-polyester composite/composite adhesively bonded joints is investigated. The study shows that the damage consists of a main crack appearing in a stress concentration zone in the adherends which then grows in the laminate first layer in a mixed mode propagation stage to the final stage leading to the ultimate failure.

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.
