摘要
Based on the large deflection beam theory and the deflection beam profile equation, a two-point bending stress determination method for ultra-thin glass plates was proposed in this paper. The full-profile bending stress distribution as the ultra-thin glass plate is bent with any contact angle and any compression displacement in the two-point bending test can be determined by the proposed method. In experiment, the widths and heights of the profile as well as the compression forces of a 100 μm thickness ultra-thin glass plate bent with different contact angles and compression displacements were measured. Measurement results of the widths and heights of the profiles as well as the compression forces are in good agreement with the theoretical values.
