Abstract (EN): The present work aims to obtain the full fracture envelopes of three different adhesives used in the automotive industry by determining the fracture energy in in mode I; mode II and various mixed-mode combinations. Double Cantilever Beam (DCB) and End-Notched Flexure (ENF) tests were performed to assess mode I and mode II fracture behaviour, while for mixed-mode analysis a versatile apparatus was used to perform a wide range of combinations from mode I to mode II. The innovative technique allows for separate determination of mode I and mode II contributions, while classical mixed-mode approaches only allow for the total to be determined. The results reveal the adequacy of the mixed-mode apparatus, presenting consistent values for the fracture energies in every mixed-mode combination studied. The fracture envelopes follow a quadratic criterion for the studied adhesives, and the results are consistent with other literature works.
