Nature of Poisson's ratio of amorphous polymers and glasses and its relation to structure-sensitive properties


Buryat State University, Smolina st. 24a, Ulan-Ude, 670000, Russian Federation

A review and analysis of studies concerning the nature of Poisson's ratio μ of glassy systems are presented. The value of μ is a more pronounced structure-sensitive property than are elasticity moduli. The unique relation of μ with the Gruneisen parameter is substantiated. In this connection, the interrelation of harmonic (linear) and anharmonic (nonlinear) characteristics is separately considered. Poisson's ratio proves to be a single-valued function of parameters characterizing dynamic properties and critical processes and is sensitive to the lattice dynamics and the atomic-molecular structure of glasses. The structural features of isotropic solids with the negative Poisson's ratio (coefficient of transverse deformation) are discussed.

Keywords: coefficient of transverse deformation, interatomic interaction potential, anharmonicity, elastic constants, amorphous organic polymers, inorganic glasses
