Abstract
Asymmetrically strengthened glass articles, methods for producing the same, and use of the articles in portable electronic device is disclosed. Using a budgeted amount of compressive stress and tensile stress, asymmetric chemical strengthening is optimized for the utility of a glass article. In some aspects, the strengthened glass article can be designed for reduced damage, or damage propagation, when dropped.
