1. Simulation-LED Strategy for Corrosion Prevention
Using multiphysics simulation, researchers at NRL are establishing the relationship between metal microstructure, pit growth, and mechanical performance
Model of pitting corrosion takes into account metal microstructure, mass transport, corrosion potential depending on crystal orientation, and uses the Moving mesh (ALE) technology for corrosion front movement
