“…In this section, we briefly review the Nitsche-inspired stabilized finite element method originally proposed in [7] for enforcing stiff cohesive laws. We will begin with a description of the strong form of the governing equations followed by the anisotropic bilinear cohesive law for mixed-mode loading.…”

“…In this paper, we illustrate the ability of the stabilized FEM of Ghosh et al [7] in alleviating traction oscillations at interlaminar interfaces in multi-directional orthotropic composite laminates under different loading conditions. A specific aim is to illustrate its robustness for composite delamination analysis, with regard to the choice of the cohesive stiffness and the structure of the finite element mesh (e.g.…”

“…Aduloju and Truster developed a DG formulation for modeling dynamic debonding in composite materials. Ghosh et al generalized Nitsche's method to enforce stiff anisotropic cohesive laws. In this way, the problem of oscillations due to spurious tractions could be overcome.…”
