In this contribution a method is introduced that allows for a linkage betweenthe process-induced structural damage and the fracture behaviour. Based on ananisotropic elastic material model, different modelling approaches for initialdamage effects are introduced and compared. The approaches are applied toremote laser cut carbon fibre reinforced polymers in order to model variousthermally induced damage effects like chemical decomposition, micro-cracks anddelamination. The dimensions of this heat affected zone are calculated with1D-heat conduction. In experiment and simulation milled and laser cut specimenswith different process parameters are compared in order to quantify the impactof the cutting technology on the fracture behaviour. For this purpose open holespecimens were used.
