Effect of Corrosive Environment Conditions on Austenitic Structure Reliability

Abstract

In this paper, the work is based on the application of probabilistic fracture mechanics models (PFM) to predict the reliability of nuclear reactors pipes under pressure. Cracking simulation of a stainless steel piping under the conditions of intergranular stress corrosion cracking (IG-SCC) is based on the general methodology recommended in the modified software M-PRAISE. IG-SCC is characterized by a unique damage parameter depending on residual stresses, environmental conditions, and sensitization degree. This parameter can be used to evaluate the structural reliability and identify the majority of efficient approaches to improve the piping reliability: effect of a corrosive medium on the reliability, which is analyzed in this present work.

Study on the Effects of Stress Corrosion Cracking (Scc) in Austenitic Stainless Steels – A Review

“…Racim BOUTELIDJA* et al, [11] explained in this paper that the work depends on the use of probabilistic break mechanics models (PFM) to foresee the dependability of atomic reactors pipes under strain. Breaking recreation of a tempered steel funneling under the states of intergranular stress consumption breaking (IG-SCC) depends on the general procedure suggested in the altered programming M-PRAISE.…”

A novel method for reliability analysis with interval parameters based on active learning Kriging and adaptive radial‐based importance sampling

“…Recent years, several classical models have been proposed to account for this type of uncertainty, including stochastic model, 7 fuzzy set model 8,9 and interval model. 10,11 Also, several researchers have made comparisons for the selection of those models and applied them into geotechnical engineering, 12 aeronautical engineering, 13 environment engineering 14 and so forth.…”
