Markov Chain Models for the Stochastic Modeling of Pitting Corrosion

Figure 1

(a) Evolution of the Generalized Extreme Value distribution fitted to the extreme pit depths predicted in a Monte Carlo framework [7] for a general soil class. The time evolution of the mean value and variance of such distributions are shown in the inset. (b) Time evolution of the functions 𝜌(𝑡) (13) and 𝑝_𝑠 (15), calculated using the predicted pitting parameters 𝜅,𝜈, and 𝑡_sd. The two curves of 𝑝_𝑠 correspond to two different values of 𝑡₀ in (15).
