“…No significant influence of the loading angle is visible which may seem surprising, as mode dependency is a commonly reported phenomenon for interface fracture toughness values (Hutchinson and Suo, 1992;Reeder and Crews, 1990). However, peel tests on these particular metal-elastomer fibrillating interfaces reveal only a negligible mode dependency (Neggers et al, 2015). These numerical results thus provide a physical explanation for the experimental observations.…”

“…To study the influence of the critical stress, a loading angle of 45 • is used. This value originates from observations in earlier work, where it was shown that the peel force in a 90 • peel test is actually transferred through the interface at an angle of approximately 45 • (Neggers et al, 2015). The critical stress is varied between p c = 0.5 MPa and p c = 4 MPa, and w = 0.01 mm.…”

“…Evidently, peel tests can be performed under various loading angles. For example, Neggers et al (2015) performed both 0 • and 90 • peel tests on (fibrillating) Cu-PDMS interfaces. Therefore, the influence of the loading angle on the work-of-separation is studied for w = 0.01 mm.…”

“…The highly nonlinear hyperelastic material response at large strains was taken into account by an Ogden model and the results were experimentally assessed using a single fibril experiment (Vossen et al, 2015). The employed fibril model clearly relies on recently reported experimental results in Neggers et al (2015) an intrinsic limitation of continuum cohesive zone models when applied to highly compliant systems for which the discrete character is essential. Finally, by studying the effect of the fibril strength on the work-of-separation, a quantitative relation between the height of the elastomer lift-off geometry (i.e.…”
