Study on dynamic response and loading mitigation characteristics of liquid-filled cell under drop-weight impact

In order to explore the anti-impact properties of the liquid-filled structure, concave and cuboid cell structures are selected for drop weight impact tests and finite element numerical analysis with and without liquid filled in the structures. Dynamic deformations were observed using high-velocity photography, and dynamic strains at typical positions were tested. The final failure modes of the cells were obtained using the 3D scanner. Then the...
