“…Presumably, the distance between the fracturing fibrils and the crack tip significantly disjoints the two processes. A similar conclusion is drawn based on a multi-scale numerical study of the same system (Vossen et al, 2014).…”

“…This is not a shortcoming of the cohesive zone model itself but a result of the employed mesoscopic approach. In a separate research is shown that this problem can be prevented by employing proper multiscale methods Vossen et al (2014Vossen et al ( , 2015.

a b s t r a c tA novel methodology is presented for pre-conditioning a polymer-coated steel used in food and beverage packaging. Mechanical rejuvenation of the coating via rolling is studied in order to prevent interface damage in subsequent forming operations. The simulations reveal that the thermodynamic state of the polymer coating after rolling depends on the rolling reduction. This dependency can be used to tailor the thermodynamic state of the coating prior to can production. A proof-of-principle simulation was performed to study the effects of rejuvenation on subsequent deformation processes. Deformation-induced interface roughening was studied for the initial and rejuvenated polymer coating. The predictions for a rejuvenated polymer coating indicate a significant decrease in interface damage.The presented numerical framework allows for a detailed study of the effects of pre-conditioning on the interface integrity during subsequent forming operations. With properly identified material parameters, it becomes possible to tailor the polymer-steel material properties before and during production to minimize interface damage during production and storage of cans or canisters, e.g. for food and beverage packaging.

“…As an alternative route, multi-scale computational methods have been proposed in Matous et al (2008) to derive the cohesive zone model response of particle reinforced adhesives by a multi-scale analysis explicitly taking into account the finite element representation of the interface microstructure. Geers and coworkers (van den Bosch et al, 2008b;Vossen et al, 2014) have also recently developed a multi-scale strategy to simulate the mechanism of fibrilation in the delamination of polymer-coated metal sheets. These investigations are based on a series of experimental works devoted to the understanding of the fibrillation processes in polymers (see Kramer and Berger (1990), Creton and Lakrout (2000), Hoefnagels et al (2010), Desai et al (2011) and the references therein given) which basically regard: (1) the voids formation along the interface, (2) the generation of load bearing crazes (fibrils), and (3) the final failure of such fibrils, leading to interface crack propagation.…”

a b s t r a c tA new cohesive zone model to describe fracture of interfaces with a microstructurs made of fibrils with statistically distributed in-plane and out-of-plane orientations is proposed. The elementary forcedisplacement relation of each fibril is considered to obey the peeling theory of a tape, although other refined constitutive relations could be invoked for the adhesive constitutive response without any lack of generality. The proposed consistent 2D and 3D interface finite element formulations for large displacements account for both the mechanical and the geometrical tangent stiffness matrices, required for implicit solution schemes. After a preliminary discussion on model parameters identification, it is shown that by tailoring the spatial density of fibrils at different orientations can be a way to realize innovative interfaces enhancing adhesion or decohesion, depending on the need. For instance, it can be possible to realize microstructured adhesives to facilitate debonding of the glass cover in photovoltaic modules to simplify recycling purposes. Moreover, the use of probability distribution functions describing the density of fibrils at different orientations is a very effective approach for modeling the anisotropy in the mechanical bonding between paper tissues and for simulating the complex process of crazing in amorphous polymers.
