Abstract

The behavior of an amorphous system, fused silica, under pressure using atomistic simulations was investigated. The Molecular Dynamic (MD) simulations of both dynamic shock loading and continuous compression at constant temperature reproduce the equation of state of flyer plate experiments. The transition between elastic and plastic behavior was correlated to changes in the ring size distribution of this glass, and was not clearly reflected by other parameters such as pair-correlation function, structure factor, or bond angle distributions.
