Abstract (EN): Adhesive joints are largely employed nowadays as a fast and effective joining process. The respective techniques for strength prediction have also improved over the years. Cohesive Zone Models (CZM's) coupled to Finite Element Method (FEM) analyses surpass the limitations of stress and fracture criteria and allow modelling damage. CZM's require the energy release rates in tension (G(n)) and shear (G(s)) and respective fracture energies in tension (G(n)(c)) and shear (G(s)(c)). Additionally, the cohesive strengths (t(n)(0) for tension and t(s)(0) for shear) must also be defined. In this work, the influence of the CZM parameters of a triangular CZM used to model a thin adhesive layer is studied, to estimate their effect on the predictions. Some conclusions were drawn for the accuracy of the simulation results by variations of each one of these parameters.
