Novel structure with negative Poisson’s ratio and enhanced Young’s modulus

In this paper, analytical and finite element (FE) 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. Opposite to similar re-entrant honeycomb structures, the new unit cell...
