Abstract

Simplification of simulation models for open-hole tensile failure of lamina-based and fabric-based CFRP laminates was discussed in this study. Various numerical studies establishing high-fidelity simulation models have been performed in the last decade. Those models have capability to predict damage progression and strength accurately by simulating all of possible damage mechanisms strictly. However, due to their high computational cost and the complexity in modelling, those models are unsuitable for the industrial field, where the reasonable compromise between accuracy and efficiency is required. A simplified simulation model which intentionally neglects damage mechanisms which have little effect on the results is proposed in this study. Instead, a less-accurate but high-efficient damage model is used. In order to investigate the effects of the modelling method on computational accuracy and time, we conducted several numerical simulations using different damage models. The results were compared with the experiments.
