Question

How can the thermal prestress be taken into account for the design value of the glass resistance?

Answer:

By selecting the "Thermally Toughened" check box, you can consider the prestress when calculating the resistance (see the image). If you select this option, Formula (2) (8.3.6/DIN18008‑1:2010‑12) will be used; otherwise Formula (3) applies.

When selecting the material, it is preselected by default, but can be adjusted by user-defined settings.
