A critical analysis of interface constitutive models for the simulation of delamination in composites and failure of adhesive bonds

Abstract: Delamination in layered composites and debonding in adhesive joints are modeled and analyzed using interfacial mechanics, consisting of interface elements for the kinematical assumption and tractionseparation equations for the constitutive model. Material equations are presented for the inelastic behavior of pure and ductile-modified epoxy resins, used for the matrix phase of the composite and in a chemically modified form for the adhesive in bonded structures.Two different modeling approaches are proposed.

“…Nossek and Marzi [21] and Matzenmiller et al [27] introduced this rate sensitivity in form of a logarithmic law similar to the Johnson-Cook model for metals [28]. The predictions obtained with this class of models have shown reasonable agreement with experimental data for dynamic mode I tests.…”

“…An accurate strength evaluation is essential when the adhesive joints are industrially introduced to new parts. Finite element analyses, such as cohesive zone models, have been used to evaluate the crack propagation problems at the joints [1][2][3][4][5]. The fracture energy is described using a local stress-displacement relationship, namely the traction-separation law.…”

“…[28][29][30] The second example therefore considers the interaction of interface debonding in a GF/PP composite with an additional adhesive layer. A homogenization approach to derive effective macroscopic cohesive properties of a microstructure was presented by Matou s et al [8,9] where microscopic damage was modeled with an isotropic continuum damage model.…”
