The main purpose of this paper is to give an overview of some recent progress made in modelling of deterioration of reinforced concrete structures. The review is not claimed to be complete. It is based on some of the author’s contributions in this research area especially the papers (Thoft-Christensen 2001) and (ThoftChristensen, Svensson and Frandsen 2005). In the paper, corrosion of reinforce...

A review of the literature and discussions with plant operators has been undertaken to establish present knowledge and understanding of the chemistry of the condensates formed on steam turbines and the link to system operation. This has been supplemented by an overview of the effect of test variables on environment assisted cracking. In Section 1, steam turbine operating conditions are describe...

The factors that have an impact upon fatigue strength are residual stress, stress concentration, the mechanical properties of the material, and the macrostructure and microstructure. Residual stress is one of the most important factors but its effect on high-cycle fatigue is of more concern than the other factors. Residual stress is a tension or compression that exists in a material without any...

Natural cases of dealloying or stress-corrosion cracking in copper alloys normally occur in oxygenated solutions, where the cathodic reactant is O2 or Cu2+. Within cavities or under deposits, the local environment is enriched in cuprous ions (e.g. CuCl2-, Cu (NH3)2+) and the potential is close to the Cu/Cu+ equilibrium. Such conditions can be simulated macroscopically by stirring powdered Cu2O ...

More than 10 years ago, the three major causes of failures in the Israel Air Force were: maintenance (-16% of failures), manufacturing (~14%), and design (-12%). While fatigue (~34%) and overload (~23%) were the two major failure mechanisms, more than 10% of failures were related to corrosion mechanisms. These include stress corrosion cracking, corrosion fatigue, localized corrosion, hot corros...
