Topology optimization for crashworthiness of thin-walled structures under axial impact using hybrid cellular automata
TL;DR: In this paper, a hybrid cellular automata (HCA) based topology optimization for thin-walled structures is presented. But, the main components of car structures are made from such thinwalled beams and panels, and a special approach using SFE CONCEPT was developed, which is presented in this paper.
