Next-Generation Modeling of Corrosion Damage Evolution

(with Prof. D. E. Brown, SIE)


We seek to develop a corrosion damage evolution model using state-of-the-art statistical analyses and probabilistic modeling methods.  The evolution model is decomposed into a corrosion initiation model and a corrosion growth model.  Each component model will account for the inherent temporal, spatial, and feature effects that govern the initiation and growth of corrosion.  This three-dimensional, probabilistic corrosion damage model will use rate descriptions from experimental measurements as inputs.  Outputs will be maps of corrosion damage as a function of exposure time, and will include calculated confidence levels for material damage.  Such maps can be used as input to life prediction or condition-based maintenance codes to increase the safety of structures and the efficiency of repair and replacement decisions.  Validation of the model by comparison to experimental data will be performed.
