verre qui claque

There are circumstances under which internal stress can build to the point of catastrophic failure when the entire sheet or object shatters into tiny pieces. This can happen if you throw a toughened ("Duralex - Made in France") glass onto concrete and is quite dramatic. The same happened with old-fashioned windscreens, which were toughened by intentionally manufacturing them with a built-in stress. This fracture mode is entirely different from cracking.

Hello

Maybe it's my imagination due to the sound of the verb but I've always understood "claquer" to be like a sudden "explosion" (almost "shatter" but not quite) whereas "fissurer" is slower and used for windscreens (not when they shatter though) and icebergs.
Maybe a native French speaker can confirm or improve on this.

Thanks for the response, but we are talking about glass manufacturing and I am not sure you would use fissure in this context?

As nouns the difference between crack and fissure is that crack is (senseid) a thin and usually jagged space opened in a previously solid material while fissure is a crack or opening, as in a rock.
Kindly check the spelling of ''augmenté'' in the French text.
