Abstract: A strengthened article (and methods for making it) is provided that includes a glass, glass-ceramic or ceramic, having a plurality of primary surfaces, side edges, and a thickness. The article also includes a compressive stress region extending from one of the primary surfaces to a first selected depth in the article; a central region extending from a boundary located at a depth of 200 μm from the primary surfaces and the edges to the centroid of the article; and an outer region extending between the primary surfaces and edges to the boundary. Further, the maximum principal stress within the outer region is no more than two times the maximum principal stress within the central region. The primary surfaces and side edges may define a plurality of corners, and the corners may be defined by a chamfer, a fillet, or a curved shape.

Abstract: A portable electronic device includes a device body containing a plurality of device structures, one of which is a display module. A cover glass is disposed at an opening of the device body such that at least one of the plurality of device structures underlies the cover glass. An energy absorbing interlayer is disposed between the cover glass and the at least one underlying device structure, where the energy absorbing interlayer has a stiffness that is lower than that of the cover glass.

Abstract: Strengthened glass-based substrates having a first outer region compressive stress and a first side having first coating thereon are disclosed. The first coating comprising a material selected to have a first coating Young's modulus value, a first coating thickness, and a first coating stress that is either neutral or compressive, such that the absolute value of first outer region compressive stress is greater than the absolute value of the first coating stress. Methods of making glass-based articles are provided, and glass-based articles having coatings that provide different strength values and/or reliability on different sides of the glass-based articles are also disclosed.

Abstract: A glass article (100) includes a core layer (102) formed from a core glass composition with a core coefficient of thermal expansion (CTE) and first (104) and second (106) cladding layers fused to first and second major surfaces of the core layer (102) and formed from a clad glass composition comprising a clad CTE. An aperture (120) extends through each of the core layer (102), the first cladding layer (104), and the second cladding layer (106). The clad CTE is less than the core CTE such that each of the first (104) and second (106) cladding layers is under a compressive stress and the core layer (102) is under a tensile stress. A flexural strength of the glass article (100) can be at least about 75 MPa. A peak load sustainable by the glass article (100) in a modified ring-on-ring test can be at most 96.5% less than a peak load sustainable by a reference glass article in the modified ring-on-ring test.
