Calculation of SCC detection and growth using a Poisson distribution

Watashi, Katsumi

A Poisson distribution well represents SCC initiation and subsequent small scale growth in material tests. This report describes the Poisson distribution application to LWR SCC database which was arranged from NUCIA. Frequencies were plotted against operated duration, then a Poisson's parameter was set to represent SCC aspect. In subsequent step, for only case, IASCC, a crack propagation was calculated. Fitting degrees of the distributions and a major parameter on failure probability were emphasized.
