  • Title: Poisson's ratio and the densification of glass under high pressure.
    Author: Rouxel T, Ji H, Hammouda T, Moréac A.
    Journal: Phys Rev Lett; 2008 Jun 06; 100(22):225501. PubMed ID: 18643428.
    Abstract:
    Because of a relatively low atomic packing density, (Cg) glasses experience significant densification under high hydrostatic pressure. Poisson's ratio (nu) is correlated to Cg and typically varies from 0.15 for glasses with low Cg such as amorphous silica to 0.38 for close-packed atomic networks such as in bulk metallic glasses. Pressure experiments were conducted up to 25 GPa at 293 K on silica, soda-lime-silica, chalcogenide, and bulk metallic glasses. We show from these high-pressure data that there is a direct correlation between nu and the maximum post-decompression density change.
