Fatigue crack growth in ceramics containing a viscous grain boundary phase at elevated temperatures
… composite was examined under tensile static loading (static fatigue) and tension-tension cyclic loading (cyclic fatigue). The study was carried out at temperatures of 700-900$\sp\circ$C, where the vitreous grain boundary phase flowed viscously. Experimental results have shown the …

Fatigue crack growth in polycrystalline alumina at high temperatures
… was examined under monotonic tensile loading (static fatigue) and under Mode-I tension-tension cyclic loading (cyclic fatigue). The investigation of fatigue crack growth in polycrystalline Al$\sb2$O$\sb3$ has confirmed the cyclic effect existing in ceramic materials, but this cyclic effect …

The structural exploitation of fibrous-cement composites in reinforced concrete T-beams
… cracking and deflection characteristics; static, fatigue and sustained loading tests are carried out on reinforced concrete T-beams cast in conjunction with asbestos-cement composites. Altogether twenty-four beams are tested, the cross-sections of which,the type and the amount of tensile …

Reliability Assessment of Optical Fibers under Tension and Bending Loads
… of optical fibers under bending loads and static fatigue conditions. This new analytic approach is verified through a simple static two-point bend experiment. Finally the newly developed reliability assessment method is used to develop new guidelines for bending application and examples are …

Long Term Durability of Glass Reinforced Composites
… study of other time-dependent effects, such as fatigue or hygrothermal degradation, and aids designers by establishing an unchanging base set of initial (undamaged) material design properties. The second portion of this dissertation discusses the effects that mean stress and R-ratio have on the …

Micromechanics-Based Strength and Lifetime Prediction of Polymer Composites
… neighbors. The experimentally verified quasi-static load sharing is incorporated into a Monte Carlo simulation for tensile strength modeling. Very good agreement is shown between the predicted and experimental strength distribution of a unidirectional composite. For the stress-rupture models a …
