Foam structures with a negative poisson's ratio
TLDR
A novel foam structure is presented, which exhibits a negative Poisson's ratio, and such a material expands laterally when stretched, in contrast to ordinary materials.Abstract:

Applicability of correlated digital image correlation and infrared thermography for measuring mesomechanical deformation in foams and auxetics
Sergej Grednev,Stefan Bronder,Francesco Kunz,Martin Reis,Susanne-Marie Kirsch,Felix Welsch,Stefan Seelecke,Stefan Diebels,Anne Jung +8 more
TL;DR: In this paper , the full field thermomechanical analysis of the mesomechanical deformation in Ni/PU hybrid foams and Ni/polymer hybrid auxetic structures performing a correlative digital image correlation and infrared thermography was compared.

Effect of twist on indentation resistance
TL;DR: In this article , the effect of twisting lattices on indentation resistance has been investigated, and it was shown that the force required to indent a twisting lattice to a set depth would increase with the amount of transverse deformation caused by twist.

Quasi-static crushing response of additive manufactured 3D reentrant circular auxetics with different polymer matrices
TL;DR: In this paper , a 3D reentrant circular (REC) auxetic metamaterial was proposed, and the effect of matrix material on the crushing behaviors of the REC specimens was examined.

The anisotropic behavior of Poisson's ratio, Young's modulus, and shear modulus in hexagonal materials
TL;DR: In this paper, a method of calculating the anisotropy of Poisson's ratio is applied to trigonal and tetragonal crystals in the literature, and the method of calculation is extended to hexagonal crystals.
