Novel images of the evolution of stress corrosion cracks from corrosion pits
TL;DR: In this article, unique three-dimensional X-ray microtomographic images have confirmed that cracks develop predominantly at the shoulder of the pit, near the pit/surface interface, for specimens stressed to 50-90% σ 0.2.
Journal ArticleDOI
New insight into the pit-to-crack transition from finite element analysis of the stress and strain distribution around a corrosion pit
TL;DR: In this article, a finite element analysis has been performed to evaluate the stress and strain distribution associated with a single corrosion pit in a cylindrical steel specimen stressed remotely in tension.

TL;DR: In this paper, two forms of high-resolution X-ray tomographic experiments (i.e., synchrotron based Xray micro-tomography and desktop microfocus computed Xray tomography) are demonstrated to illustrate the wide application of these techniques for qualitative and quantitative studies of localised corrosion and environmentally assisted cracking.
Journal ArticleDOI
Challenges in modelling the evolution of stress corrosion cracks from pits
TL;DR: In this article, a preliminary mathematical model based on deterministic equations with statistically variable input parameters was developed for simulating the evolution of the pit depth distribution at different exposure times, and the transformation to stress corrosion cracks was based on the Kondo criteria.
Journal ArticleDOI
Effect of stress corrosion cracking on stress–strain response of steel wires used in prestressed concrete beams
TL;DR: In this paper, an experimental study of the stress corrosion cracking (SCC) process on 8mm-diameter wires which are used industrially in precast concrete prestressed by pre-tension is presented.

Prediction of Fatigue Crack Initiation Life Based on Pit Growth
TL;DR: In this article, the fatigue crack initiation behavior of low-alloy steel in 90 C deionized water was investigated and it was observed that the corrosion fatigue process composed three stages, namely, pit growth and pit growth.
Journal ArticleDOI
Unification of the deterministic and statistical approaches for predicting localized corrosion damage. I. Theoretical foundation
TL;DR: In this paper, the authors provide an alternative theoretical basis for damage function analysis (DFA), by drawing an analogy between the growth of a pit and the movement of a particle, leading to the original expressions for the damage functions for active (living) and passivated (dead) pits, and hence for the differential and integral damage functions, as were obtained from the original theory.
Journal ArticleDOI
A model to predict the evolution of pitting corrosion and the pit-to-crack transition incorporating statistically distributed input parameters
TL;DR: In this paper, a model based on deterministic equations with statistically distributed input parameters has been developed for simulating the evolution of the pit depth distribution at different exposure times and the percentage of pits that transform to stress corrosion cracks.

A. Turnbull,S. Zhou +1 more
TL;DR: In this article, the authors reviewed the effect of material properties (steel cleanliness, yield strength), environment (oxygen, carbon dioxide, chloride level), temperature, and stress conditions, on the initiation and growth of stress corrosion cracks.
