Blast mitigation using polymeric 3D printed auxetic re-entrant honeycomb structures: A preliminary study

نویسندگان

چکیده

Protection of critical infrastructure in an urban environment is a challenging task, specifically against the vehicle bourne improvised explosive device threat. To design to withstand this evolving threat, novel solutions and advanced materials need be developed. One such material interest are auxetics. This study experimentally analysed mitigation blast response auxetic re-entrant honeycomb structures, with geometries varying between ?ve 30° +ve using additive manufacturing (3D printing) techniques non-explosive loading via shock tube. Re-entrant structures (?ve 15°) exhibited repeatable 23% reduced transmitted pressure impulse wave. Further highlighting their potential application as protective measure enhance survivability.

Hierarchical honeycomb auxetic metamaterials

Most conventional materials expand in transverse directions when they are compressed uniaxially resulting in the familiar positive Poisson's ratio. Here we develop a new class of two dimensional (2D) metamaterials with negative Poisson's ratio that contract in transverse directions under uniaxial compressive loads leading to auxeticity. This is achieved through mechanical instabilities (i.e., b...

A review on auxetic structures and polymeric materials

Auxetic polymeric materials are a special kind of materials that exhibit negative Poisson’s ratio (NPR) effect. They get fatter when stretched and thinner when compressed. Auxetic behavior is a scaleindependent property which can be achieved at different structural levels from molecular to macroscopic levels. The internal structure of material plays an important role in obtaining auxetic effect...

3D-Printed Biodegradable Polymeric Vascular Grafts.

Congenital heart defect interventions may benefit from the fabrication of patient-specific vascular grafts because of the wide array of anatomies present in children with cardiovascular defects. 3D printing is used to establish a platform for the production of custom vascular grafts, which are biodegradable, mechanically compatible with vascular tissues, and support neotissue formation and growth.

Mechanical Properties of Auxetic Cellular Material Consisting of Re-Entrant Hexagonal Honeycombs

A preliminary study of the mechanical properties of auxetic cellular material consisting of re-entrant hexagonal honeycombs is presented. For different scales of the honeycombs, the finite element method (FEM) and experimental models are used to perform a parametric analysis on the effects of the Poisson's ratio (cell angle) and the relative density (cell thickness) of honeycombs on bearing cap...
