Failure started at the edges of the lap regions and propagated to the centres of the adhesive-bonded single-lap joints. The force–displacement curves indicate that too rigid a film anticipates and accelerates damage to the cohesive elements because of the rigid behaviour making the material more fragile and less resilient. The experimental and simulation results are compared in Fig. 10a and 10b. The comparison allows the numerical model to be quantitatively validated, revealing a good fit with the experimental data.
