Abstract

Bonded joints are highly sensitive to the presence of defects and to the degradation phenomena,and this aspect represents the primary obstacle to their use in different structuralengineering applications. Delamination in a bonded joint represents, in fact, one of the primary,most common and insidious causes of damage. In this paper, a numerical–experimentalstudy on the crack propagation along the adhesive layer of a bonded joint specimen is carriedout. Experimental study is focused on the evaluation of the damage modalities of a bondedjoint when the specimens are subject to fatigue load. Experimental tests are compared withthe results of several numerical analysis performed in ANSYS environment. A crack growthmodel is implemented in the finite element method solver and allows the simulation of theprogressive delamination process. Comparison between numerical results and experimentaltests allows to identify the descriptive numerical parameters of fatigue crack propagation,which may be used in the structures design.
