...Yan Wang; Peng Yan; Xi Wang; Bingzhi Chen Purpose Metal thin-walled tubes are commonly employed in energy absorption devices due to their lightweight and exceptional energy absorption capabilities. However, traditional circular tube stack energy absorption systems are susceptible to transverse...

... Hz). Eigenmodes of the dispersion curves were analyzed to investigate the BG formation mechanisms. The dependence of BG opening and closure on structure parameters was also studied. Finally, the energy absorption property of the QZS metastructure was evaluated by comparing it with a classical model...
