An extensive experimental work for Pyroceram[TM] 9606 glass-ceramic was conducted to determine static fatigue at ambient temperature in distilled water. This work was an extension and companion of the previous work conducted in dynamic fatigue. Four different applied stresses ranging from 120 to 170 MPa urn incorporated with a total of 20-23 test specimens used at each of four applied stresses. The slow crack growth (SCG) parameters n and D were found to be n = 19 and D = 45 with a coefficient of correlation of [r.sub.coef] = 0.9653. The Weibull modulus of time to failure was in a range of [m.sub.sf] = 1.6-1.9 with an average of [m.sub.sf] = 1.7 [+ or -] 0.2. A life prediction using the previously determined dynamic fatigue data was in excellent agreement with the static fatigue data. The life prediction approach was also applied to advanced monolithic ceramics and ceramic matrix composites (CMCs) based on their dynamic and static fatigue data determined at elevated temperatures. All of these results indicated that a SCG mechanism governed by a power-law crack growth formulation was operative, a commonality of SCG in these materials systems. [DOI: 10.1115/1.4028393]
