TL;DR: In this article, a mathematical model has been developed to describe the mass transport and electrochemical conditions in a corrosion fatigue crack in steel cathodically protected in sea water, and the effects on crack tip pH, potential and molecular hydrogen concentration of varying the external potential, ΔK (range of the stress intensity factor), R value (minimum load/maximum load), crack depth and frequency at a temperature of 5°C were investigated.

TL;DR: In this paper, a plot of plane strain fracture toughness vs. tensile yield strength for ultra-high strength steels (UHSS) and beta-Ti alloys precipitation hardened with a phase is presented.
Abstract: : Two important advances over the past 40 years enable the optimization and management of the structural integrity of components in high performance applications. First, the solid mechanics conununity established linear elastic fracture mechanics as the premier framework for modeling the damage tolerance of fracture critical components (Irwin and Wells, 1997; Paris, 1998). Second, materials scientists developed metals with outstanding balances of high tensile strength and high fracture toughness (Garrison, 1990; Wells, 1993; Boyer, 1993; Starke and Staley, 1995; Olson, 1997; Kolts, 1996). An example of achievable strength-toughness properties is provided in Fig. 1, a plot of plane strain fracture toughness vs. tensile yield strength (sigma-YS) for ultra-high strength steels (UHSS) and beta-Ti alloys precipitation hardened with a phase (Gangloff 2001). New nano-scale characterization and high performance computational methods provide for additional advances in the mechanical performance properties of structural metals. These modem alloys and analysis tools satisfy technological needs for optimization and management of component performance in demanding fatigue and fracture critical applications in the aerospace, marine, energy, transportation, and defense sectors.

TL;DR: In this paper, a critical evaluation of mechanistically based modelling of environment-assisted cracking has been made, namely slip-dissolution, anodic reaction-induced cleavage and surface mobility, from both a mechanistic and quantitative perspective.

TL;DR: In this paper, a critical evaluation of empirical and mechanistically based modelling of pit propagation kinetics has been made, which assumes that the material and environmental conditions are nominally uniform in the regions of interest, and variations in conditions with time are difficult to account for.
Abstract: A critical evaluation of empirical and mechanistically based modelling of pit propagation kinetics has been made. Empirical models of pit growth kinetics based on the application of Faraday s law to measurement of the total current flowing to potentiostatically controlled specimens have the limitation that only average properties are measured and have limited practical relevance. Extreme value statistics applied to materials exposed for varying periods of time provide a more effective method of prediction of maximum pit depths at a given time. However, the approach assumes that the material and environmental conditions are nominally uniform in the regions of interest, and variations in conditions with time are difficult to account for. Mechanistically based models are more flexibile and more informative from the viewpoint of understanding. However, absolute prediction of pit growth kinetics in service conditions is uncertain because of specific limitations in input data. An implicit fitting to exp...
