摘要：
In this study, three novel types of hierarchical reentrant honeycomb structures were designed, which comprised subunits with a semi-reentrant, reentrant, and hexagonal honeycomb. These ships of those structures were established. The out of plane compression behavior and deformation characteristics were investigated through finite element simulations and experiments. It was shown that the hierarchical structure composed of reentrant subunits had the best mechanical properties among three structures. The hierarchical structure composed of the classic hexagonal honeycomb subunit exhibited plastic deformation characteristic spreading from the middle and upper layers to the whole region during compression.
