Concurrent numerical implementation of vibration correlation technique for fast buckling load prediction of cylindrical shells under combined loading conditions
As a non-destructive buckling experimental technique, the vibration correlation technique (VCT) is extensively applied in buckling load prediction of columns, plates and shells under axial compression load. Fo...

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 ...

Mechanical properties of bio-mimetic energy-absorbing materials under impact loading
The elytra can protect the body and hind wings of the beetle by absorbing the impact energy and resisting damage from outside loading. In this paper, we firstly observed the microstructures of hollow column an...
