Abstract

The crack-sized c and the strength distributions of structural ceramics after non-destructive inspection (NDI) were analysed by supposing penny-shaped cracks to be inner cracks. The theoretical crack-size distribution function after NDI coincides well with the experimental data for a three-point bending test of HP-Si3N4 in the regiond c > 30μm. The distribution function of the fracture strength calculated from the crack-size data after NDI coincides well with the experimental data.
