Abstract
Glass-based articles are frangible, comprising a peak central tension (CT) in a tensile region that is greater than: (E/68 GPa)*75 MPa*1 mm/√(t), where E is the Young's modulus value of the glass-based substrate utilized to form the glass-based article. The stress profiles of the glass-based articles may comprise: a maximum compressive stress (CS) greater than or equal to 150 MPa; a depth of compression (DOC) that is greater than or equal to 0.21; a peak central tension (CT) in a tensile region that is greater than or equal to 100 MPa to less than or equal to 220 MPa; and/or a negative curvature region, wherein a second derivative of stress as a function of depth is negative.
