A glass-based substrate comprises: a glass transition temperature (Tg), a liquid fragility index (m), and fictive temperature (Tf), wherein Tg is less than or equal to 650° C., a value of Tf minus Tg is greater than or equal to −30° C., and m is greater than or equal to 25. A stress relaxation rate is greater than or equal to 10%, or 20% or more. The articles can comprise a lithium-based aluminosilicate composition and a fracture toughness that is greater than or equal to 0.75 MPa*m0.5. The stress profiles comprise: a spike region extending from the first surface to a knee; and a tail region extending from the knee to a center of the glass-based article, the tail region comprising: a negative curvature region wherein a second derivative of stress as a function of depth is negative; a depth of compression (DOC) that is greater than or equal to 0.22 t, and a parabolic region originating at the DOC and extending to the center of the glass-based article.
