AbstractDefects, such as pores and scratches, are inevitably introduced during preparation and processing of ceramics. How they affect the mechanical properties of materials is worthy of attention. Here, artificial surface pores and notches introduced by femtosecond/nanosecond lasers are regarded as inherent pore- and scratch-like defects. Bending test results indicated that a small-sized flaw with the length and depth of similar to 10 mu m could lead to a strength reduction up to similar to 40% in sharp flaw case, while only slight attenuation (< 10%) occurs in blunt flaw case. Linear extrapolation result reveals that the maximum strength in notch cases, when the depth reaches the atomic scale, is similar to 34 GPa, which is in the range of the theoretical value of 24-48 GPa. Furthermore, the calculated critical flaw size (a(c)) may tend to be overestimated, given that the artificial defect, which is smaller than the ac value, also results in significant strength decay. This study could provide guidance for strength evaluation and high-strength design of ceramics.
