Fatigue crack growth in ceramics containing a viscous grain boundary phase at elevated temperatures
Elevated-temperature crack growth behavior in a commercial Al$\sb2$O$\sb3$ and a hot-pressed 30 vol.% TiB$\sb2$-SiC composite was examined under tensile static loading (static fatigue) and tension-tension cyclic loading (cyclic fatigue). The study was carried out at temperatures of …

The Effects of Load Ratio on Threshold Fatigue Crack Growth of Aluminum Alloys
… structures are threatened by the presence of cracks. Structural failure occurs if a crack larger than a critical size exists. Although most well designed structures initially contain no critical cracks, subcritical cracks can grow to failure under fatigue loading, called fatigue crack growth …
