Measurement for Elastic Modulus of Ultra-Thin Glass by Cantilever Beam Method

Abstract:

In order to overcome the limitations of common methods for measuring elastic modulus of the ultra-thin glass，a novel method is proposed for measuring the elastic modulus of the ultra-thin glass by cantilever beam vibration method．The measurement principle，apparatus，and manipulation were introduced. In this method, the measured ultra-thin glass is generated in the form of a cantilever beam, and the cantilever beam can be vibrated for a short time when transient excitation is applied. The natural frequency of the cantilever beam can be used to calculate the elastic modulus of the ultra-thin glass material. A series of ultra-thin glass samples with different thickness were tested in this work, the measured values are consistent with that given . The effect of beam length/thickness ratio on determination of elastic modulus of materials by means of cantilever method was analyzed, the result shows that the influence of the ratio can be neglected if the beam length is equal to or more than 10 times of the beam thickness.
