Failure of classical elasticity in auxetic foams
J. H. Roh, C. B. Giller, P. H. Mott +1
A recent derivation [P.H. Mott and C.M. Roland, Phys. Rev. B 80, 132104 (2009).] of the bounds on Poisson's ratio, v, for linearly elastic materials showed that the conventional lo…

Limits to Poisson's ratio in isotropic materials - general result for arbitrary deformation
P. H. Mott, C. M. Roland
The lower bound usually cited for Poisson's ratio ν is -1, derived from the relationship between ν and the bulk and shear moduli. From consideration of the longitudinal and biaxial…

Limits to Poisson's ratio in isotropic materials
PH Mott, CM Roland
A long-standing question is why Poisson's ratio v nearly always exceeds 0.2 for isotropic materials, whereas classical elasticity predicts v to be between -1 to 1/2. We show that t…
