Patent ID: 11827559

Abstract:
Frangible glass articles having a fracture behavior that resists ejection of glass particles upon fracture. In some embodiments, the frangible glass articles can have a first surface region with a first elastic compressive stress energy per unit area of glass (Welcomp1), a second surface region with a second elastic compressive stress energy per unit area of glass (Welcomp2), and a central region with an elastic tensile stress energy per unit area of glass (WT), where (Welcomp1+Welcomp2)−WT≤25 J/m2. In some embodiments, the frangible glass articles can have a total load ratio (Wi/GD) less than 6.5 and a total elastic compressive stress energy per unit area of glass (WC) less than 60% of a total load (Wi), where: WC=Welcomp1+Welcomp2, Wi=WC+WT, GD=4G1C, and In some embodiments, the frangible glass articles can have a differential load ratio (Wd/GIC) less than
