Abstract: Apparatus and methods for impact testing of a transparent substrate are provided. The apparatus includes a base (110) for receiving the transparent substrate (112), the base having a curved surface (124) about which the transparent substrate is bent by a first fixture (130) and a second fixture (132). An abrasive sheet (136) is disposed between the transparent substrate and an impacting object (138) which is released from above the substrate such that the force from the impacting object causes damage to the transparent substrate while the transparent substrate is bent about the curved surface.

Abstract: Glass-based articles are disclosed having a thickness in a range of from about 0.2 mm to about 4.0 mm, a first compressive stress layer extending from a first surface of the glass-based article to a first depth of compression that is in a range of from about 5% to about 20% of the thickness, a second compressive stress layer extending from a second surface of the glass-based article to a second depth of compression that is in a range of from about 5% to about 20% of the thickness, wherein the second surface is opposite the first surface, and a central region extending from the first depth of compression to the second depth of compression and having a maximum tensile stress in a range of from about 0.5 MPa to about 20 MPa. Electronic devices comprising the glass-based articles and methods of making glass-based articles are also disclosed.

Abstract: Chemically strengthened glass articles having at least one deep compressive layer extending from a surface of the article to a depth of at least about 45 μm within the article are provided. In one embodiment, the compressive stress profile includes a single linear segment extending from the surface to the depth of compression DOC. Alternatively, the compressive stress profile includes two linear portions: the first portion extending from the surface to a relatively shallow depth and having a steep slope; and a second portion extending from the shallow depth to the depth of compression. The strengthened glass has a 60% survival rate when dropped from a height of 80 cm in an inverted ball drop test and an equibiaxial flexural strength of at least 10 kgf as determined by abraded ring-on-ring testing. Methods of achieving such stress profiles are also described.

Abstract: Chemically strengthened glass articles having at least one deep compressive layer extending from a surface of the article to a depth of layer DOL of about 130 μm up to about 175 μm or, alternatively, to a depth of compression (DOC) in a range from about 90 μm to about 120 μm within the article. The compressive layer has a stress profile that includes a first substantially linear portion extending from a relatively shallow depth to the DOL or DOC and a second portion extending from the surface to the shallow depth. The second portion is substantially linear at a depth from 0 μm to 5 μm and has a steeper slope than that of the first portion of the profile. Methods of achieving such stress profiles are also described.
