Abstract
Embodiments of glass articles including a compressive stress (CS) region and a central tension (CT) region, wherein a portion of the CS region extends from the first major surface to a depth of compression (DOC), wherein, when the glass article is in a substantially flat configuration, the CT region has a maximum value (CTflat) that is about 60 MPa or less, and wherein, when the glass article is in a cold bent configuration, CT region comprises a maximum value (CTbent), wherein CTbent/CTflat<1.4. Embodiments of automotive interior systems including such glass articles are provided, along with methods for forming a glass article and for forming an automotive interior system are also disclosed.
