A detailed study on a silicon nitride reinforced with silicon carbide whiskers has been undertaken on room temperature fatigue during static and dynamic loading at constant DK. It is shown that sub-critical crack growth rates are lower when the material experiences sustained far field loading than d

The results of an experimental study designed to determine the temperature dependence of salt water-inhanced fatigue crack growth are presented in this paper. It was found that the rate of crack-growth is constant over an extended range of crack-tip intensity. The activation energy calculated from s
AbstractΓThe mechanisms of cyclic fatigue-crack propagation in a grain-bridging ceramic, namely an in situ toughened, monolithic silicon carbide, is examined. The primary goal is to directly quantify the bridging stresses as a function of cyclic loading. To investigate the eect of the number of load
