Abstract (EN): in this paper, delamination during drilling of carbon/epoxy plates is analysed using the finite element method. The composite plate is modelled by successive layers, allowing the usage of different stacking sequences. The tool is modelled as a 'rigid body', and different tool geometries are compared, as well as axial thrust forces and delamination onset. The model simulations consider non-linear three-dimensional analysis and include the use of previously formulated interface finite elements incorporating a damage model based on fracture mechanics. Results are compared with experimental data. Important conclusions were drawn in order to decrease the probability of delamination occurrence.
