Orientational ordering induced by shear deformation in an amorphous Lennard-Jones solid
Abstract
An amorphous Lennard-Jones solid has been severely deformed in a shearing manner by using computer molecular-statics techniques. The orientational order parameter Q6 is significantly increased before the onset of the shear localization. Computer-generated optical diffraction patterns show that a phase with explicit sixfold symmetry in one projection, and with fourfold and twofold symmetry in the other two projections (a tendency towards a close-packed layer structure) appears in the severely deformed system. The radial distribution functions, however, show no apparent crystallization occurring. © 1986 The American Physical Society.
