Effective usage of multiphysics calculation for crevice corrosion

Yamamoto, Masahiro 

Recently, some attempts using Multi-Physics simulation for corrosion problems, especially crevice corrosion, have been increasing. Corrosion undergoes by electrochemical reaction. The numerical calculation procedure is used a non-liner equation. Furthermore, this reaction is affected by environmental factors, i.e. composition, amount and mobility of chemical species and redox potential. These values change with time by corrosion process itself. This report, these needs for Multi-Physics calculations are introduced.
