  • Patent number: 10962457
    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.
