Next-Generation
Modeling of Corrosion Damage Evolution
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.
