Time to failure was estimated by using a mathematical function that describes the crack shielding developed during subcritical crack growth. Such results were compared with experimental fatigue lives obtained in Y-TZP/PSZ materials. From this it may be concluded that the initial slope of crack shielding curves greatly influences the time to failure. ER -
