fabrication process, including standard acquired and manufactured parts. Experimental validation was accomplished by fabricating DCB-type specimens and testing with different mode ratios to verify the correct functioning and repeatability of results for the same mode-mixity. This process was accomplished using the P -  data, and the following work will consist of measuring the fracture energies and construction of the fracture envelope of adhesives for final validation by comparison with literature data, leading to a complete methodology to characterize the mixed-mode behaviour of adhesive joints.
