Failure prediction in glass fiber reinforced plastics laminates with drilled hole under uni-axial loading

Drilling induced damage in fiber reinforced plastic laminates results in high rate of parts rejection and also affects the in-service performance of the composite products with drilled holes. The tensile testing of composite laminates with drilled holes is necessary to render them satisfactory for application. The present research endeavor is an attempt to develop a generic finite element model in order to investigate to failure of uni-directional glass fiber reinforced plastics (UD-GFRP) composite laminates with drilled hole under uni-axial tensile testing. The results have been compared with the experimental work done earlier and are found to be in good agreement.
