Design and mechanical properties analysis of hexagonal perforated honeycomb metamaterial

International Journal of Mechanical Sciences, Год журнала: 2024, Номер 270, С. 109091 - 109091

Опубликована: Фев. 7, 2024

Hexagonal perforated honeycomb (HPH) metamaterials were designed, fabricated and investigated in this work. Initially, the mechanical properties deformation modes of various proposed HPH (HPH-U, HPH-1L HPH-3L) under quasi-static vertical compression analyzed using experimental finite element methods. The findings reveal significant improvements energy absorption due to hierarchical expandable design. Notably, auxetic effect is diminished. Subsequently, impact key dimensional parameters on Poisson's ratio behavior was explored. results highlighted that an increase elliptical perforation major axis minor enhanced but compromised load-bearing absorptive capacity. Additionally, displayed exceptional performance horizontal compression, with their structure enabling them withstand both impacts while exhibiting excellent capabilities. study also identified relative density as a crucial factor influencing performance. Finally, subjected multiple repetitive compressions, meticulously analyzing variations diverse ratios. Due distinctive structural design impressive properties, demonstrate immense potential for applications automotive engineering sports protection fields.

Multi‐Physical Lattice Metamaterials Enabled by Additive Manufacturing: Design Principles, Interaction Mechanisms, and Multifunctional Applications

Advanced Science, Год журнала: 2025, Номер unknown

Опубликована: Янв. 20, 2025

Abstract Lattice metamaterials emerge as advanced architected materials with superior physical properties and significant potential for lightweight applications. Recent developments in additive manufacturing (AM) techniques facilitate the of lattice intricate microarchitectures promote their applications multi‐physical scenarios. Previous reviews on have largely focused a specific/single field, limited discussion properties, interaction mechanisms, multifunctional Accordingly, this article critically design principles, structure‐mechanism‐property relationships, enabled by AM techniques. First, are categorized into homogeneous lattices, inhomogeneous other forms, whose principles processes discussed, including benefits drawbacks different fabricating types lattices. Subsequently, structure–mechanism–property relationships mechanisms range fields, mechanical, acoustic, electromagnetic/optical, thermal disciplines, summarized to reveal critical principles. Moreover, metamaterials, such sound absorbers, insulators, manipulators, sensors, actuators, soft robots, management, invisible cloaks, biomedical implants, enumerated. These provide effective guidelines
