|Title:||R-curve effect on strength and reliability of toughened ceramic materials|
|Citation:||Duan, K., Mai, Y.-W., Cotterell, B. (1995-01). R-curve effect on strength and reliability of toughened ceramic materials. Journal of Materials Science 30 (6) : 1405-1408. ScholarBank@NUS Repository. https://doi.org/10.1007/BF00375239|
|Abstract:||An improved theoretical analysis is presented for the strength and mechanical reliability of ceramic materials with an R-curve characteristic. There is good agreement between the predicted flexural strength distribution of an Al2O3/ZrO2 ceramic and experimental datA. Unlike the conventional two-parameter Weibull approach, this new analysis is able to predict the non-linearity observed in the lnln 1/(1-Pf) versus In σf strength distribution curve. Compared to the untoughened Griffith material, the R-curve material has higher strength and better strength reliability. © 1995 Chapman & Hall.|
