Abstract: An apparatus for testing the edge strength of a discrete sheet of material such as glass where the sheet has an irregular free-form shaped outline is disclosed. The apparatus can include a plurality of assemblies configured for selectively applying a 3-point bending load on an edge of the sheet of material in a test region of the apparatus, a detection mechanism that optically measures strain in the sheet of material in the region, and a processor that determines the stress in the sheet based on the measured strain by calculating the stress that would be required to produce the measured strain in the sheet of material.

Abstract: Disclosed are embodiments of a glass article for a vehicle interior system. The glass article includes a glass sheet with a first side and a second side. A first frame is disposed on the glass sheet on the first side of the glass sheet, and a second frame disposed on the second side of the glass sheet. A mandrel is disposed between the first frame and the second frame. The mandrel has a flexural rigidity of at least 150 Pa·m3 and a density of at most 2.75 g/cm3. The second side of the glass sheet rotates about the mandrel from a first configuration to a second configuration. In the first configuration, the first side forms a first angle with the second side, and in the second configuration. the first side forms a second angle with the second side. The first angle is different from the second angle.

Abstract: A bendable glass article having a bendable display unit is disclosed. The glass article includes a glass sheet including a first major surface and a second major surface opposite to the first major surface. A hinge mechanism is disposed on the second major surface of the glass sheet. The hinge mechanism divides the glass sheet into a first side and a second side. A bendable display unit is bonded to the second major surface of the glass sheet and disposed between the glass sheet and the hinge mechanism. An adhesive material is disposed on the second major surface of the glass sheet around the display. The first side is bendable about the hinge mechanism relative to the second side, and the bendable display unit is hermetically sealed within the adhesive material.

Abstract: A laminate glass article is provided that includes: a core glass layer comprising a first coefficient of thermal expansion (CTE); and a plurality of clad glass layers, each comprising a first primary surface, a second primary surface in contact with the core glass layer and a second CTE that is lower than the first CTE of the core glass layer. The difference in the first and second CTE is about 10×10−7/#C to about 70×10−7/#C. Further, each of the core glass layer and the clad glass layers comprises a viscosity from 109.0 to 1014.0 Poise from about 550 #C to about 700 #C.

Abstract: Glass articles including one or more 3D printed surface features attached to a surface of a substrate at a contact interface between the 3D printed surface feature and the surface. The 3D printed surface feature(s) include a glass or a glass-ceramic, a compressive stress region at an exterior perimeter surface of the 3D printed surface feature(s), and a central tension region interior of the compressive stress region. The 3D printed surface feature(s) may be formed of a contiguous preformed material 3D printed on a surface of a substrate. The compressive stress region of a 3D printed surface feature may be formed using an ion-exchange process.

Abstract: Apparatus can comprise a cavity at least partially defined by a first major surface of a reference block and configured to receive a sample. The apparatus can comprise a first polarization-switching light source configured to emit a first polarization-switched light beam toward the cavity and a first detector configured to detect a corresponding signal. The apparatus can comprise a second polarization-switching light source configured to emit a second polarization-switched light beam toward the cavity and a second detector configured to detect a corresponding signal. The first reference block can be positioned between the second detector and the second reference block. Methods of determining an estimated stress profile can comprise determining a central tension from a measured retardation profile of the sample. Methods can comprise determining an initial stress profile from a refractive index profile of the sample. Methods can comprise scaling and adjusting stress profiles.
