Notes:
This paper deals with the application of Cohesive Zone Model (CZM) concepts to study mode Ifracture in adhesive bonded joints. In particular, an intrinsic piece-wise linear cohesive surfacerelation is used in order to model fracture in a pre-cracked bonded Double Cantilever Beam (DCB)specimen. Finite element implementation of the CZM is accomplished by means of the user element(UEL) feature available in the FE commercial code ABAQUS. The sensitivity of the cohesive zoneparameters (i.e. fracture strength and critical energy release rate) in predicting the overallmechanical response is first examined; subsequently, cohesive parameters are tuned comparingnumerical simulations of the load-displacement curve with experimental results retrieved fromliterature
