Numerical, theoretical, and experimental studies on the energy absorption of the thin-walled structures with bio-inspired constituent element

Nowadays, more bio-inspired structures were proposed and adapted in structural designs to improve their energy absorbing performance. In this paper, a bio-inspired constituent element (BCE) consisting of a hollow cylindrical tube with four panels was studied. Quasi-static tests were conducted to evaluate its energy-absorbing performance using specimens with a thin-walled square tube. A FE model was developed and validated in favorable agreement...
