- Abstract
- <jats:title>Abstract</jats:title><jats:p>During industrial glass production processes, the actual distribution of stress components in the glass during scribing remains, to date, poorly quantified, and thus continues to be challenging to model numerically. In this work, we experimentally quantified the effect of pressure and temperature on the viscosity of <jats:styled-content style="fixed-case">SCHOTT</jats:styled-content> N‐<jats:styled-content style="fixed-case">BK</jats:styled-content>7<jats:sup>®</jats:sup> glass, by performing in situ deformation experiments at temperatures between 550 and 595°C and confining pressures between 100 and 300 MPa. Experiments were performed at constant displacement rates to produce almost constant strain rates between 9.70 × 10<jats:sup>−6</jats:sup> and 4.98 × 10<jats:sup>−5</jats:sup> s<jats:sup>−1</jats:sup>. The resulting net axial stresses range from 81 to 802 MPa, and the finite strains range from 1.4% to 8.9%. The mechanical results show that the <jats:styled-content style="fixed-case">SCHOTT</jats:styled-content> N‐<jats:styled-content style="fixed-case">BK</jats:styled-content>7<jats:sup>®</jats:sup> glass is viscoelastic near the glass transition temperature at 300 MPa of confining pressure. To elucidate the data, we incorporated both 1‐element and 2‐element generalized Maxwell viscoelastic models in an inversion approach, for which we provide <jats:styled-content style="fixed-case">MATLAB</jats:styled-content> scrips. Results show that the 2‐element Maxwell model fits the experimental data well. The stress decreases with increasing temperature at 300 MPa and the temperature dependence yields a similar activation energy (601 ± 10 kJ mol<jats:sup>−1</jats:sup> or ∆<jats:italic>H</jats:italic>/<jats:italic>R</jats:italic> = 7.2 × 10<jats:sup>4</jats:sup> K) to a previously reported value at 1‐atm (615 kJ mol<jats:sup>−1</jats:sup> or ∆<jats:italic>H</jats:italic>/<jats:italic>R</jats:italic> = 7.4 × 10<jats:sup>4</jats:sup> K). The <jats:styled-content style="fixed-case">SCHOTT</jats:styled-content> N‐<jats:styled-content style="fixed-case">BK</jats:styled-content>7<jats:sup>®</jats:sup> glass shows a limited linear increase in viscosity with increasing pressure of ~0.1 log<jats:sub>10</jats:sub> (Pa·s)/100 MPa, which is in agreement with the most recent 2‐internal‐parameter relaxation model (based on experiments).</jats:p>
