Fracture Behavior of Silicon Carbide Measured by Different Test Methods

摘要：

Single edge notched beam (SENB) and indentation methods (IM) were used to test the fracture toughness (KIc) of SiC ceramic in present work. Both of testing results were compared. The applicative computational equation of indentation crack was determined through studying indentation morphology formed by IM. The results showed that the indentation crack in SiC could be Babcock crack,and the Kic value calculated by Niihara (P) indentation equation approximated to real value mostly with minimum relative deviation.
