Multi-cell energy-absorbing structures with hollow columns inspired by the beetle elytra
In this work, we propose a new type of thin-walled energy-absorbed structure with hollow columns that possesses a design inspired by the beetle elytra. The failure mode of the bionic thin-walled structures is ...
