| Abstract Scope |
Understanding long term aging and chemical compatibility of an assembly of materials is challenging, particularly when the mechanisms include incompatibilities with vapors and gases from outgassing of other materials in the assembly. These aging mechanisms manifest slowly and can be difficult to investigate with accelerated aging experiments.
We have developed a reactive transport modeling capability for moisture and demonstrated its use on several scales ranging from single material to multi-material level. Our physics based numerical ReSorT-M (i.e. Reaction Sorption Transport and chemo-Mechanics) model is a triple-mode sorption model that is coupled to a Fickian diffusion model. Our materials span polymers, composites, and metals. In this talk, we will present the ReSorT workflow and several of its applications to multi-materials system.
