A novel re-entrant auxetic honeycomb with enhanced in-plane impact resistance
TL;DR: In this paper, a reentrant star-shaped honeycomb (RSH) was proposed and the in-plane impact responses explored theoretically and numerically, and three types of microstructural deformation modes were observed under different impact velocities, including low-velocity mode, medium-velcocity mode and high-vel cation mode, and a deformation map was summarized to illustrate the effects of the impact velocity and the relative density on the deformation mode.
Journal ArticleDOI
Novel structure with negative Poisson’s ratio and enhanced Young’s modulus
TL;DR: In this article, analytical and finite element simulations are carried out to calculate the in-plane Poisson's ratio and Young's modulus of a novel concept of structure with honeycomb-like configuration under uniaxial loading.
Journal ArticleDOI
Microstructure and mechanical properties of three-dimensional five-directional braided composites
TL;DR: In this article, three types of microstructural unit cell models are established with respect to the interior, surface and corner regions of 3D five-directional braided composites.
Journal ArticleDOI
In-plane dynamic crushing behaviors of a novel auxetic honeycomb with two plateau stress regions
TL;DR: In this paper, a novel honeycomb structure with higher energy absorption capacity was proposed by adding double arrowhead honeycomb (DAH) cells into star-shaped honeycomb, and therefore named as star-arrow head honeycomb.
Journal ArticleDOI
Novel auxetic structures with enhanced mechanical properties
TL;DR: In this paper, two novel auxetic cellular structures are proposed, with the Young's modulus and yield strength of the auxetic structures significantly enhanced and without sacrifice of their negative Poisson's ratio in the corresponding perpendicular direction.
