Discussion of "a Molecular Dynamics Simulation Study of the Cavitation Pressure in Liquid Al"

Abstract

The recent report by Hoyt and Potter using molecular dynamics to simulate cavitation in liquid aluminum selects an unusually low value for the interatomic potential, which leads to an unusually low value for the tensile strength of liquid Al. A revised value for the interatomic potential results in a cavitation pressure consistent with other estimates of this parameter. © 2013 The Minerals, Metals & Materials Society and ASM International.
