Abstract: Glass-based articles comprise stress profiles providing improved drop performance. A glass-based substrate comprises: a glass transition temperature (Tg), a liquid fragility index (m), and fictive temperature (Tf), wherein Tg is less than or equal to 650° C., a value of Tf minus Tg is greater than or equal to −30° C., and m is greater than or equal to 25. A stress relaxation rate is greater than or equal to 10%, or 20% or more. The articles can comprise a lithium-based aluminosilicate composition and a fracture toughness that is greater than or equal to 0.75 MPa*m0.5. The stress profiles comprise: a spike region extending from the first surface to a knee; and a tail region extending from the knee to a center of the glass-based article, the tail region comprising: a negative curvature region wherein a second derivative of stress as a function of depth is negative; a depth of compression (DOC) that is greater than or equal to 0.22t, and a parabolic region originating at the DOC and extending to the center of the glass-based article.

Abstract: Glass-based articles having defined stress profiles and methods for manufacturing such glass-based articles are provided. A non-limiting glass-based article comprises an outer region extending from the surface to a depth of compression, wherein the outer region is under a neutral stress or a first compressive stress, a core region under a second compressive stress, the second compressive stress defining a compression peak having a maximum compression value and a maximum width at zero stress in a range of from about 1 micrometer to about 200 micrometers, and an intermediate region disposed between the surface and the core region, wherein the intermediate region is under a tensile stress.

Abstract: A laminated glass article includes a glass core layer having a core modulus Ecore and a glass cladding layer adjacent to the core layer and having a cladding modulus Eclad. Eclad can be at least 5 GPa less than Ecore. A modulus ratio Ecore/Eclad can be at least 1.08. The cladding layer can have a compressive stress resulting from a coefficient of thermal expansion (CTE) contrast between the core layer and the cladding layer and/or subjecting the laminated glass article to an ion exchange treatment to form an ion exchanged region at an outer surface of the cladding layer.
