“…During the test, a wedge, in touch with two adhesive surfaces, is drawn along the length direction of the specimen. [ 78,82 ] The values of peel strength measured using wedge peel tests, corresponded with the results by fracture mechanics methods. [ 78 ] The third method is the twist peel test (Figure 4 c) to qualitatively characterize the adhesive strength of coating in the winding wire industry.…”

Nature often exhibits various interesting and unique adhesive surfaces. The attempt to understand the natural adhesion phenomena can continuously guide the design of artificial adhesive surfaces by proposing simplified models of surface adhesion. Among those models, a peeling model can often effectively reflect the adhesive property between two surfaces during their attachment and detachment processes. In the context, this review summarizes the recent advances about the peeling model in understanding unique adhesive properties on natural and artificial surfaces. It mainly includes four parts: a brief introduction to natural surface adhesion, the theoretical basis and progress of the peeling model, application of the peeling model, and finally, conclusions. It is believed that this review is helpful to various fields, such as surface engineering, biomedicine, microelectronics, and so on.

“…To meet different situations of surface contact, [74][75][76][77][78][79][80] four kinds of methods based on peeling model have been developed to characterize the surface adhesive force ( Figure 4 ). The most commonly used method is that peeling one end of the sample from the substrate at a certain angle (Figure 4 a).…”

“…Interests in bonding of thin metal adherends of relevance to the automotive industry have driven the development and adoption of several wedge tests that induce large plastic bending of the adherends. Knowing the radius of curvature of the debonded adherends and the elastic-plastic properties of the adherends, one can calculate the fracture energy of the adhesive either statically [28] or for dynamically loaded specimens such as the impact wedge peel (IWP) test [29].…”

A driven wedge test is used to characterize the mode I fracture resistance of adhesively bonded composite beam specimens over a range of crosshead rates up to 1 m=s. The shorter moment arms (between wedge contact and crack tip) significantly reduce inertial effects and stored energy in the debonded adherends, when compared with conventional means of testing double cantilever beam (DCB) specimens. This permitted collecting an order of magnitude more crack initiation events per specimen than could be obtained with end-loaded DCB specimens bonded with an epoxy exhibiting significant stick-slip behavior. The localized contact of the wedge with the adherends limits the amount of both elastic and kinetic energy, significantly reduces crack advance during slip events, and facilitates higher resolution imaging of the fracture zone with high speed imaging. The method appears to work well under both quasi-static and high rate loading, consistently providing substantially more discrete fracture events for specimens exhibiting pronounced stick-slip failures. Deflections associated with beam transverse shear and root rotation for the shorter beams were not negligible, so simple beam theory was inadequate for obtaining qualitative fracture energies. Finite element analysis of the specimens, however, showed that fracture energies were in good agreement with values obtained from traditional DCB tests. The method holds promise for use in dynamic testing and for characterizing bonded or laminated materials exhibiting significant stick slip behavior, reducing the number of specimens required to characterize a sufficient number of fracture events.

“…Carlberger and Stigh (2007) show that the strain rate in an adhesive is amplified compared to the joined material, implying that dynamic adhesive material parameters are better determined in adhesive joints and not through bulk material testing. Blackman et al (2000) perform a critical review of the standard ISO 11343 for impact wedge-peel testing of adhesives. This method is used to evaluate crash resistant adhesives for the automobile industry.…”

Effects of temperature and strain rate on the cohesive relation for an engineering epoxy adhesive are studied experimentally. Two parameters of the cohesive laws are given special attention: the fracture energy and the peak stress. Temperature experiments are performed in peel mode using the double cantilever beam specimen. The temperature varies from −40 to +80 • C. The temperature experiments show monotonically decreasing peak stress with increasing temperature from about 50 MPa at −40 • C to about 10 MPa at +80 • C. The fracture energy is shown to be relatively insensitive to the variation in temperature. Strain rate experiments are performed in peel mode using the double cantilever beam specimen and in shear mode, using the end notch flexure specimen. The strain rates vary; for peel loading from about 10 −4 to 10 s −1 and for shear loading from 10 −3 to 1 s −1 . In the peel mode, the fracture energy increases slightly with increasing strain rate; in shear mode, the fracture energy decreases. The peak stresses in the peel and shear mode both increase with increasing strain rate. In peel mode, only minor effects of plasticity are expected while in shear mode, T. Carlberger (B) SAAB Automobile AB, the adhesive experiences large dissipation through plasticity. Rate dependent plasticity, may explain the differences in influence of strain rate on fracture energy between the peel mode and the shear mode.
