The present study addresses the simulation of layer debonding along thick interfaces in dynamic regime by means of the use of a cohesive interface model accounting for geometrical and material nonlinear effects. This novel simulation approach has been framed within the finite element method. Numerical examples assess the influence of different interface parameters, such as the adhesive thickness and the effect of the imposed displacement velocity, in relation to 90° peeling tests. The obtained results pinpoint the relevance of the interplay of geometric and material nonlinear effects, which can notably modify the peak-force and the post-peak response evolution of the system in dynamics.
