Abstract : The present work deals with the finite element simulation of drilling of fibre-reinforced composites. The simulation is done using commercially available software. Hashin failure criteria has been used to simulate the drilling process. Three dimensional drill model was created and Hashin failure is defined via VUMAT sub-routine. Three-dimensional Hashin failure have larger stress and strain analysis resolution. This research is focused on validating reaction force and accuracy of drill. Reaction force obtained in composite drilling simulation is compared with experimental data. The work is focused on reproducing the simulation of composite modelling and composite damage rather than theoretical explanation of composite material and mathematical model behind the simulation. Thus, laying the knowledge to simulate composite fibres failure.
