Mechanical metamaterials with multi-level dynamic crushing effects (MM-MLs) are designed in this study through coordinate transformation and mirror arrays. The mechanical of the diameter length ratio struts connecting rods, Euler angles, cell numbers on properties investigated separately. MM-ML can exhibit significant two-level platform stress, local cells first stress stage undergo rotational motion, while second mainly involves collapse compression bending. Although increasing rods increase range Poisson's ratio, it will reduce level energy absorption. Increasing angle strain interval improve absorption capacity. In addition, number maintaining a constant relative density effectively enhance has parameter controllability, achieve different regions, ranges ratios, requirements according to application scenario, demonstrate functional diversity compared existing research. design scheme provide ideas for adaptive protection requirements.

This study proposes a new, doubly re-entrant auxetic unit-cell design that is based on the widely used honeycomb structure. Our objective was to develop structure preserves and enhances advantages of while eliminating all negative aspects. The geometry aims enhance mechanical properties, buckling deformation characteristic mechanism. effects geometric modification are described evaluated using two parameters, offset deg. A series experiments were conducted wide range parameters these parameters. Specimens printed via vat photopolymerization process subjected compression test. aim investigate properties (energy absorption compressive force) behaviour specimens in relation relevant novel achieved intended outperforming original Increasing deg results increasing energy capability (up 767%) maximum force 17 times). right parameter choice eliminates continuous behaviour. Finally, dependency predicted by analytical approximation as well.
