cohesive material with mechanical properties obtained from previous experimental testing (Table 2). Therefore, it is expected that the model estimates the peel strength based on mechanical properties taken from more common experimental tests, i.e., bulk, thick adherend shear test (TAST), end-notched fracture (ENF) test, double cantilever beam (DCB) test. Finally, the rollers were modelled as rigid non deformable surfaces.

Figure 2. Kinematic representation of the testing jig and the adhesive joint with respect to the system's rotation centre.

The interaction between the rollers and the testing jig fulcrum was established through connector elements (Abaqus beam), as shown in Figure 3.
