A cold-formed glass laminate may include a first ply of 3D formed glass with a first thickness and a first strength. The first ply may include pre-formed residual compressive stresses in a peripheral edge portion adapted to offset tensile stresses resulting from a cold-forming process. The laminate may also include a second ply of 3D formed glass with a second thickness less than the first thickness and a second strength greater than the first strength. An adhesive may be arranged between the first ply and the second ply and post-formed residual stresses in the peripheral edge portion of the first ply of the laminate may remain compressive. A method of forming a glass laminate with compressive edge stresses is also described.

A cold-formed glass laminate (100) may include a first ply (108) of 3D formed glass with a first thickness, a first strength, and a first coefficient of thermal expansion. The laminate (100) may also include a second ply (110) of 3D formed glass with a second thickness less than the first thickness, a second strength greater than the first strength, and a second coefficient of thermal expansion. The second coefficient of thermal expansion may be selected to be sufficiently higher than the first coefficient of thermal expansion to induce residual compressive stresses in the first ply (108) due to cold forming therewith. An adhesive layer (112) may be arranged between the first ply (108) and the second ply (110).
