Abstract Scope |
The majority of stress corrosion cracking (SCC) models are conventional statistical fits to empirical SCC growth rate databases or one dimensional physically based models accounting for far field loading conditions and macroscopic material properties, yet it is reasonable to think local conditions dictate intergranular cracking behavior. Presented in this paper is a method to model SCC of 304 stainless steel at elevated temperature in high purity water within the framework of a large strain formulation of the elasto-viscoplastic fast Fourier transform (LS-EVPFFT) model. The model enables large-scale explicit microstructure sensitive modeling of SCC sequentially after plastic deformation of the structure inducing localized conditions for SCC. Realistic three-dimensional intergranular SCC morphologies are achieved to reveal the role of heterogeneities in mechanical fields over explicit three-dimensional grain microstructures and grain boundary character distributions in promoting/suppressing stress corrosion cracking. |
