Introduction Nowadays ceramics have been used in structural components due to hardness and light weight.
However, the fatigue crack growth rate of ceramics is not only affected by the effective stress intensity factor range, ΔKeff, because the crack growth rates of ceramics are susceptible to the tensile stress ahead of a crack tip [1].
