Multiobjective optimization of perforated square CFRP tubes for crashworthiness

Open holes and cutouts have been widely used in composite structures for various engineering purposes. However, perforation could largely alter the structural responses and crashing behavior, thereby creating significant challenge in composite design. This study carried out a parametric study and design optimization on the perforation parameters for the perforated carbon fiber reinforced plastic (CFRP) square tubes to improve the structural...
