Strength Specification for 0.55mm Thickness Specialty Materials 4 O.7 MM Thickness Specification Specialty Materials 5 Specialty Materials 6 Strength of glasses • Strength of glass is a measure of the distribution of the largest flaws in the test samples – Largest flaw in a specimen controls strength: weak link theory – All discussions about strength pertain to flaws – For glasses before ion-exchange, there is a relation between flaw size and measured strength. • Small flaw →High strength • Large flaw →Low strength • Flaws are induced by – Machining – Handling – In-use condition such as sharp or blunt impact • Discussions about glass strength should include questions like – How was the glass made? – Where and how were the samples finished? – What is their manufacturing and handling history?
