Corning, producatorii celebrei sticle Gorilla Glass, care protejeaza sute de milioane de smartphone-uri, inclusiv iPhone-ul, prezinta intr-un clip video procesul de spargere a unui ecran, dar si duritatea Gorilla Glass 2. Acest din urma produs a fost lansat special pentru smartphone-urile anului 2012, Samsung Galaxy S III il contine deja si se speculeaza ca iPhone 5 il va folosi. Clipul ne demonstreaza ca Gorilla Glass 2 este mai rezistent decat orice alt concurent de pe piata, insa doar in cazul loviturilor, nu si in cazul zgarieturilor.
Strength is the relationship between the surface compression and inner tension; it determines, among other things, how many blows a piece of glass can endure before it shatters completely. Glass only breaks in tension, when the force of impact finally overcomes the surface compression. A scratch doesn’t shatter glass, but small stresses will eventually lead to a colossal splintering.
