Paper Title:
Three-Dimension Reconstruction of Pit Corrosion Damage Morphology and Digital Simulation
  Abstract

According to the various grey values at different regions in an image, a three-dimension (3D) solid model is reconstructed based on the pitting corrosion damage data obtained from the pre-corrosion accelerated experiment which is performed under four different time levels: 12h, 24h, 48h and 72h by CAD. An analysis procedure is developed using finite element analysis to predict stresses and the crack nucleation site due to corroded pits. Based on the observations on fatigue fracture section, the AFGROW software is used to simulate the influence of a variety of corrosion damages and corrosion pit depths on the specimen’s residual fatigue life. An effective and reliable engineering method for predicting fatigue life of corroded specimen is established on the base of this research work.
