Measurement of Elastic Constants for Composite Materials by 3-Point Bending, Twisting and Impact Sound Test


Article Preview

Analyzing a sound produced by an impact of a fallen ball upon a small rectangular bar specimen, elastic moduli of engineering ceramic composites can be determined. In this paper,three-points bending and torsional test devices which employed the specimen for the impactsound test were designed. Using the devices, elastic moduli of various materials were mea-sured applying deformation theory. The elastic constants evaluated by the impact sound testwere compared with those measured by the devices. They agreed well. A reliable measure-ment system was developed for elastic constants of anisotropic materials.
