This paper presents a global/local approach for the nonlinear analysis of thin-walled composite structures. While the global model is built in NASTRAN, the local model is based on refined structural theories with superior computational efficiency and accuracy. The results prove the convenience of using higher-order models for the local domain to reduce computational overheads.
