This book presents papers on fracture mechanics and mechanism of ceramic composites, a crack growth resistance model for fiber-reinforced ceramic materials, the fracture toughness of carbon fiber reinforced ceramic composites, microstructures and fracture behaviors at high temperatures for Al2O3-SiC nanocomposites, and the subcritical crack growth of macro- and microcracks in ceramics. Particular attention is given to the R-curve properties of alumina, measured by stable fracture test in bending; the R-curve behavior of alumina and PSZ at ambient and high temperatures; the crack-resistance curve and cyclic fatigue in ceramic materials; the fatigue behavior of nonoxide ceramics at elevated temperature; and crack growth in zirconia-bearing ceramics under cyclic loading. Also discussed is an approach on the lifetime prediction for ceramics under elevated temperature with static fatigue, an indirect method for the determination of da/dN - Delta K curves for ceramic materials, and the effect of surface charge on subcritical crack growth in glass.
