Probabilistic failure of a cracked submarine pipeline and subjected to the underwater shock

The failure of a cracked submarine pipeline subjected to the underwater explosion shock is probabilistically analyzed in this paper. A simple procedure is presented, in which the Monte Carlo method is used to estimate the bending stress distribution, and an analytical method is used to estimate the...
