Abstract (EN): The design of composite structures used in jet-engines in the presence of stress concentrations, such as bolted or riveted joints, is a critical step for the effective use of composite materials and for the reduction of structural weight. Recent developments on analysis methods did not account for the relevant out-of-plane failure modes of bolted joints (pull-through). An experimental and numerical study is presented on the pull-through failure modes in carbon fibre reinforced plastic (CFRP). Assuming bolted joint failure at the first damage event, when the sub-critical failure load is reached, a numerical three-dimensional finite element model is proposed to predict the onset of damage. Numerical analysis models show good agreement between the experimental data and initial sub-critical predicted load.
