Abstract

The deformation and fracture of a soda-lime-silica glass were investigated under tension by molecular dynamics simulation. The process of the deformation consisted of elastic deformation, flow, and expansion accompanied with flow in the order before the glass fractured. The main structural change on each deformation was the expansion of Si-O-(Al, Si) angle, change of network rings, and growth of cavity. The cavities were generated in the region where non-bridging oxygen ions clustered and grew up in the region where Ca ions clustered in addition to the clustered non-bridging oxygen ions. The fracture time became shorter and the fracture strain and volume decreased with increasing tension.
