Abstract
The deformation of the soda lime silica glasses made by different cooling rate under pressure and stress were investigated by MD simulation. Two kinds of glasses were made by cooling from 3000 K to 300 K for 10 ps and 500 ps, respectively. Rapid cooling glass has the structure with more 3- and 4-membered rings and more dispersed distribution of modifier ions than that in slow cooling glass. Under pressure and stress, the deformed volume and strain of rapid cooling glass was larger than those of slow cooling glass. The difference of deformation between these glasses was due to the difference of network structure.
