| Abstract: | The measurement of K IC values by cylindrical four point bend specimen with circumferential sharp notch was proposed in this paper. This type of measurement can directly determine K IC values of ductile material under brittle fracture by small specimen. This method is simple, economical and can give accurate results. |
