Structure change of soda-silicate glass by mechanical milling

Numerical Simulation of Soda-Lime Silicate Glass Tempering

The paper deals with the computation of residual and transient stresses in a tempered glass plate. The modelling takes into account the viscoelastic behavior and the structural relaxation of glass. The evolution of stresses with time during the rapid cooling is computed. Simulation results are compared with experimental ones from the literature available. Levels of transient tensile stress in t...

Structure and topology of soda-lime silicate glasses: implications for window glass.

The structural and topological properties of soda-lime silicate glasses of the form (1-2x)SiO2-xNa2O-xCaO are studied from classical molecular dynamics using a Buckingham type potential. Focus is made on three compositions (x = 6%, 12%, and 18%) which are either silica-rich or modifier-rich. We compare the results to available experimental measurements on structural properties and find that the...

Mechanical response of sodium silicate glass

We propose a new method using coarse-graining and molecular dynamics to calculate structural and mechanical properties for sodium silicate glasses at different scales. Using this method we were able to describe the mechanical behavior of the material, this way a new constitutive model was developed which could be used in continuum calculations.

Effect of KNO3 Molten Bath Na Enrichment on the Mechanical Performances of Ion-exchanged Soda-Lime- Silicate Glass

Systematic doping of pure molten KNO3 bath by sodium nitride was used to analyze the effect of salt poisoning on the mechanical performances of chemically tempered soda-lime-silicate float glass. The ion-exchange process appears partially influenced by the presence of limited amount of Na in the potassium nitride bath. The interdif‐ fusion coefficient and the penetration depth of K are invarian...
