NRC Predicts Corrosion in Multimaterial Car Structures with Apps

Danick Gallant, NRC, Canada

To achieve fuel efficiency goals, conventional materials for car structures, such as structural steel, must be combined with lighter materials, such as aluminum. Scientists at the National Research Council Canada (NRC) develop corrosion-resistant multimaterial assemblies containing both aluminums and steels as well as optimize the cost-effective processes for their mass production. NRC employed multiphysics simulation to develop mathematical models and simulation apps capable of predicting corrosion behavior that speed up the development of corrosion-resistant assemblies and drive innovation in automotive lightweighting.
