Elastic Modulus Determination of Coating Layers as Applied to Layered Ceramic Materials

Authors: Chin Chen Chu, Eldon D. Case

Abstract

This paper develops relationships for determining the in-plane elastic modulus of a coating by two experimental techniques: (1) dynamic resonance and (2) static bend. Dynamic resonance measurements on model two-layer and three-layer composite beams (consisting of bonded strips of alumina and glass) agree well with the relationships developed. In addition, the dynamic resonance and static bend techniques are applied to a SiC coating/graphite substrate composite, where the two methods give statistically similar results for the elastic modulus of the SiC coatings.
