Abstract

MAINLY DUE TO THEIR LOW WEIGHT, LOW COST AND EASE OF ASSEMBLY, THE ADHESIVE BONDS HAVE EMERGED AS A PROMISING TECHNOLOGY. HOWEVER, THE LACK OF ADEQUATE TOOLS OF DESIGN AND CONTROL REMAIN AN OBSTACLE TO THE USE OF THE ADHESIVES. IN THIS WORK A COHESIVE INTERFACE MODEL FORMULATED WITHIN THE FRAMEWORK OF DAMAGE MECHANICS IS APPLIED FOR THE SIMULATION OF DECOHESION DURING CRACK PROPAGATION TESTS. CONSIDERING THE MECHANICAL TESTS OF ALUMINIUM/EPOXY SPECIMENS, COMPARISONS BETWEEN EXPERIMENTAL AND NUMERICAL RESULTS ARE PRESENTED.
