“…Figure 19 shows the load-displacement curve at the end of one of the two arms of the specimen. The global response until the complete failure of the specimen agrees with the theoretical solution calculated for a beam on an elastic foundation [16] using linear fracture mechanics theory for the propagation [3]. The difference in slope which can be observed before the softening part of the curve is due to the fact that the damage law used in the calculation enables damage to take place progressively before the rupture of a point.…”

International audienceThis paper investigates a computational strategy for studying the interactions between multiple through-the-width delaminations and global or local buckling in composite laminates taking into account possible contact between the delaminated surfaces. In order to achieve an accurate prediction of the quasi-static response, a very refined discretization of the structure is required, leading to the resolution of very large and highly nonlinear numerical problems. In this paper, a nonlinear finite element formulation along with a parallel iterative scheme based on a multiscale domain decomposition are used for the computation of 3D mesoscale models. Previous works by the authors already dealt with the simulation of multiscale delamination assuming small perturbations. This paper presents the formulation used to include geometric nonlinearities into this existing multiscale framework and discusses the adaptations that need to be made to the iterative process in order to ensure the rapid convergence and the scalability of the method in the presence of buckling and delamination. These various adaptations are illustrated by simulations involving large numbers of DOFs

“…The adhesion energy of the coating on PMMA was quantified using the asymmetric double cantilever beam (ADCB) test. − The asymmetric specimen configuration was specially chosen to confine the debond occurring at the interface of soft polymer substrate and hard coating. − The specimens (Figure ) were prepared by bonding an uncoated thinner substrate onto a coated thicker substrate using epoxy adhesive [E-20HP Hysol High Strength Epoxy Structural Adhesive, Henkel AG & Company, Düsseldorf, Germany]. The in-plane dimensions of the specimen were 9 mm × 70 mm.…”

“…The specimens were loaded with a displacement rate of 5 μm/s in tension to produce controlled coating debonding, followed by unloading. The load was measured simultaneously, and the adhesion energy, G c (J/m 2 ), was calculated from the critical value of the strain energy release rate. − …”

Carbon-bridges were successfully incorporated into the molecular structure of inorganic silicate films deposited onto polymer substrates using an oxidative atmospheric plasma deposition process. Key process parameters that include the precursor chemistry and delivery rate are discussed in the context of a deposition model. The resulting coating exhibited significantly improved adhesion and a 4-fold increase in moisture resistance as determined from the threshold for debonding in humid air compared to dense silica or commercial sol-gel polysiloxane coatings. Other important parameters for obtaining highly adhesive coating deposition on oxidation-sensitive polymer substrates using atmospheric plasma were also investigated to fully activate but not overoxidize the substrate. The resulting carbon molecular bridged adhesive coating showed enhanced moisture resistance, important for functional membrane applications.

“…An interface stiffness of the same order as the beam material's Young's modulus can be regarded as a rigid interface [18], but there is no unanimous agreement on the exact value in the literature (see, for example, Refs. [19,20,21]). For application to composite DCBs, the interfacial stiffness can be determined by 3 0…”
