Based on the previous experiment on the statistical nature of the crack initiation life t_i and the crack propagation life t_p in stress corrosion cracking of a high strength steel in 3.5% NaCl, the distribution of the total lives t_f (=t_i+t_p) is studied theoretically assuming that both t_i and t_p follow Weibull distributions. It is shown that t_f follows a composite Weibull distribution approximately. This composite Weibull distribution is similar to the distribution of t_p in the shorter life region, and to that of t_i in the longer life region. The bent portion moves downwards on Weibull probability paper with an increase in the average ratio of t_i to t_p. The concepts of "initiationdominated distribution" and "propagation-dominated distribution" are proposed. Furthermore, a new interpretation of a composite Weibull distribution is presented.
