Summary
A general feature of glassy materials is a strong nonlinear flow rule relating stress and strain. This feature is no well-documented and poorly understood. Many have tried to understand the glass transition by studying the dynamical heterogeneities in glass-forming materials, but Using a local velocity measurement technique, the authors measure the local flow of a film of confined glassy material.
