Environmental effects on the reliability of an AISI 304 structure

Environmental effects on the reliability of an AISI 304 structure

This work is based on the application of probabilistic fracture mechanics (MRP) models to predict the reliability of pressure pipelines in nuclear power reactors. The simulation of cracking of stainless steel piping under the conditions of intergranular stress corrosion cracking (IGSCC) is based on...
