英文摘要Here, the limitations of characteristic length-based (L-chb) and grain size-based (G(b)) criteria with two or three parameters were pointed out employing the apparent toughness tests of 12 different ceramics at a large span range of U-notch root radius (& rho;) values. After comprehensively considering the potential influencing factors of stress intensity factor (K-c), & rho; divided by critical notch tip radius (& rho;(c)) was proposed as the independent variable, and the data of 21 materials (covering ceramics, plastics, resins, rocks, and metals) was summarized and discussed to establish a simple and more applicable K-c prediction model. Results indicated that K-c/K-Ic was a power function of & rho;/& rho;(c) with a power exponent n of 0.5 for ideal materials and less than 0.5 for actual materials. It was also found that & rho;(c) can be calculated simply by K-Ic(2)/(& pi;& sigma;(2)(0)), where & sigma;(0) represented the inherent strength. This semiempirical criterion succeeded in unifying the L-chb and G(b) criteria without introducing more parameters to increase the prediction accuracy of the K-c at the U-notch root for brittle materials like ceramics.
