Advanced Modular Honeycombs with Biomimetic Density Gradients for Superior Energy Dissipation

Biomimetics, Год журнала: 2025, Номер 10(4), С. 221 - 221

Опубликована: Апрель 3, 2025

The honeycomb configuration has been widely adopted in numerous sectors owing to its superior strength-to-weight ratio, rigidity, and outstanding energy absorption properties, attracting substantial academic attention research interest. This study introduces a biomimetic modular inspired by the variable-density biological enhancement characteristics of tree stem tissues. examined out-of-plane compressive behavior mechanical structures. A numerical model was constructed utilizing finite element technology, enabling simulation studies at varying impact velocities. improved weight-bearing impact-absorbing properties structures are investigated using theoretical analysis computer simulations. It also scrutinizes effects boundary matching conditions on honeycomb’s performance. results indicate that adjusting thickness walls both matrix sub-honeycomb can substantially improve their resistance low-velocity compression impacts. Furthermore, capacity honeycombs during high-velocity impacts is significantly influenced multiple factors: velocity, density structure, distribution wall within primary matrix. Notably, with an optimally designed structure demonstrates high-speed compared conventional equivalent density. These insights underscore potential for advanced designs further advance material performance structural applications.
