Two kinds of theory for non-destructive inspection of ceramics were reviewed, which were derived by the authors using flaw-size distribution. In the sufficient condition theory (Realistic NDI), we had discussed about the screening flaw-size and a screening region. In the necessary and sufficient condition theory (Ideal NDI), we found that the screening flaw-size should be changed depending on stress state and specimen configuration. It was proved that there is one-to-one correspondence between Ideal NDI and a proof test. Applications to machining damage problems and surface strengthening of ceramics were also presented.

Hole Structure

This paper outlined the experimental and theoretical study on the TC4 alloy fasten holes structure to assess the first inspection and maintenance period for structures. The initial fatigue quality of the fastener holes was represented by an equivalent initial flaw size distribution. Based on the experimental results of crack size, the life of fasten structure detail in which 5% crack happened was provided and the resulted life was suggested as the structure economical life. The predicated economical life of titanium alloy fasten hole structure are helpful to the economical repair of the airframe structure.
