A Survey of Compression Studies on Silicon Carbide (SiC)

Abstract

Compression of a solid material under plane shock wave propagation/ loading can provide information related to change in density and shear strength with pressure/stress of the material under inertial confinement. The present work surveys and analyzes the existing shock compression and high-pressure data on silicon carbide to provide pertinent information to material modelers and others for use in their work related to this material. It also points out a set of investigations that needs to be carried out to complement the existing data.u Acknowledgments

“…In the paper written by Dandekar (2002), it was found that 6H-Sic is manufactured by Cercom and is marketed as SiC-B, so the data for 6H-SiC has been included in this data report. Table E-3 has the bulk modulus data for 6H-SiC, as reported by Dandekar (2002).…”

“…In the paper written by Dandekar (2002), it was found that 6H-Sic is manufactured by Cercom and is marketed as SiC-B, so the data for 6H-SiC has been included in this data report. Table E-3 has the bulk modulus data for 6H-SiC, as reported by Dandekar (2002). The data in Dandekar's paper comes from two separate experiments: Bassett et al (1993) and Yoshida et al (1993) B 0 represents the bulk modulus, B 0 ' is the pressure derivative of the bulk modulus and P max is the maximum pressure to which the experiments were carried out (Dandekar, 2002).…”

Bassett et al (1993) and Yoshida et al (1993) confined the SiC material in a mixture of sodium chloride and gold, and methanol, ethanol and water respectively, to produce a hydrostatic pressure environment in their samples (Dandekar, 2002). et al (1993) Figure E-1 shows the mean volumetric compression of 6H-SiC from the studies completed by Bassett et al (1993) and Yoshida et al (1993).…”

“…The hydrodynamic compression of SiC-B is represented by the bulk modulus and the pressure derivative of the bulk modulus; this is information is summarized in Table E-4. The information in this table was reported by Dandekar (2002) and was collected from two studies completed by Kobayashi (1997, 1998). In Table E-4, HEL represents the Hugoniot Elastic Limit.…”

“…In Table E-4, HEL represents the Hugoniot Elastic Limit. Kobayashi (1997, 1998) took this value from the work done by Bassett et al (1993) for their analyses (Dandekar, 2002). Figure E-2 shows a plot of shock compression data for various forms of SiC, generated by various investigators.…”
