Negative Poisson’s ratios in metal nanoplates [PDF]
Nature Communications, 2014 The Poisson's ratio is a fundamental measure of the elastic-deformation behaviour of materials. Although negative Poisson's ratios are theoretically possible, they were believed to be rare in nature. In particular, while some studies have focused on finding or producing materials with a negative Poisson's ratio in bulk form, there has been no such ...

Negative compressibility, negative Poisson's ratio, and stability [PDF]
physica status solidi (b), 2008 AbstractThe role of negative compressibility is considered in detail. Experimental observations of negative bulk modulus in pre‐strained foam are presented and interpreted. A constrained microscopic model which exhibits negative compressibility is proposed.

Effect of a Negative Poisson Ratio in the Tension of Ceramics [PDF]
Physical Review Letters, 2008 The effect of a negative Poisson ratio is experimentally revealed in the tension deformation of a natural layered ceramic. This effect can increase the volume strain energy per unit volume by 1100% and, simultaneously, decrease the deformation strain energy per unit volume by about 44%, so that it effectively enhances the deformation capacity by about ...
