Research Description

Multiple-Impact Testing of Single-Crystal SiC
Single-crystal silicon carbide (SiC) is a candidate material as window shields for military and VV1P vehicles, as protection equipment for law-enforcement officers during riots, and as transparent armor for many defense applications. It has good transparency, high hardness, and high elastic modulus. Although considerable research has been conducted in literature on polycrystalline SiC, the effectiveness of single-crystal SiC against impact has not been well studied. Another issue of equal or greater interest is its ability to withstand multiple impacts in hostile environment. In this research project, a fundamental investigation of the impact response of single-crystal silicon carbide will be modeled using indentation technique. The damage developed due to a diamond Vickers indentation will be analyzed to rationalize the effect of indenter orientation with respect to the SiC single crystal orientation. The induced damage due to the multi-hit loading will be modeled by conducting two sequential indentations at various separation distances and at various orientations of the single crystal. The relative orientations of the indentations in relation to the single crystal orientation will induce different cracking patterns which can be analyzed to investigate the material removal volume during multi-hit conditions. By analyzing the crack lengths and their interaction response, one can assess, at a fundamental level, the multi-hit resistance of single crystal SiC. I intend to complete this research and write a manuscript with intent to submit to a peer-reviewed journal for publication.
