Description
The corrosion in the pipelines of pressurized water reactor is a catastrophic event, leading to the ultimate fracture and failure [1,2,3]. Herein, we develop a real-time framework for the accumulation of compressive stresses via coupling corrosion-induced and the internal/external fluid pressure, where the former causes the irreversible (plastic) deformation the latter leads to the reversible (elastic) compression. In this regard, we quantify the real-time infiltration of the oxygen within the metal matrix in the curved boundary, leading to the augmentation in the volume [4] and we compute stoichiometrically the resulted equivalent oxide thickness. Subsequently, we compute the accumulated compressive stress in real time from both elastic and plastic events, which could be used as a measure for anticipation of the onset of mechanical failure. The developed analytical framework could be utilized for quantifying the design parameters for safe operation of the transport pipes, particularly in applications related to the high-pressure and highly corrosive environments.
Keywords: Corrosion Stress, Elastic Stress, Curved Boundary, Inner/Outer Corrosion, Mechanical Failure.
