Abstract
The increase in fatigue life under a constant applied load, due to the pres ence of crack shielding, was studied. Time to failure was estimated by usin g a mathematical function that describes the crack shielding developed duri ng subcritical crack growth. Such results were compared with experimental f atigue lives obtained in Y-TZP/PSZ materials. From this it may be concluded that the initial slope of crack shielding curves greatly influences the ti me to failure.
