Webb6 okt. 2015 · The strength of a material is the amount of stress that it can withstand before fracturing. For a perfect theoretical glass, the strength is defined as. where γf is the energy of the fractured surface, Y is Young’s modulus, and a0 is the distance between atoms in the glass. This typically ends up being on the order of GPa (gigapascals (109 Pa).
