Abstract Scope |
The design of robust and reliable metals that are simultaneously strong and corrosion resistant is crucial for various applications where high mechanical stress and corrosive environment coexist. In this work, a finite element analysis-based multiphysics model was developed to investigate and predict the corrosion behavior of aluminum alloys when simultaneously subjected to surface stress using experimentally obtained mechanical and corrosion properties as inputs. The model not only accounts for pure corrosion and mechanical deformation behavior, but also incorporates the stress-corrosion synergy effects by correlating the equilibrium corrosion potential with the amounts of elastic and plastic deformation. Finally, surrogate models were used for uncertainty quantification of the finite element model. |
