| Abstract Scope |
Because hydrogen is stored and transported in various forms, predicting the microstructure evolution and macroscopic properties changes of materials under complex boundary conditions requires a flexible and adaptive modeling scheme. This work proposes a modularized multiscale and multiphysics material modeling platform for assessing hydrogen effects on metallic materials’ behavior. We will demonstrate its applications on steel components for the hydrogen storage and transport segment, including the liquid hydrogen storage tank, large diameter line pipe for longer pipe runs, and hydrogen compressor. The modeling platform consists of 7 interdependent submodules: atomistic modeling toolset, hydrogen uptake models, hydrogen-induced phase transformation models, hydrogen transport models, continuum model of hydrogen effects on plasticity, hydrogen-aware fracture model, and macroscopic hydrogen-sensitive model. Besides advancing in modeling, the modularized concept will support the data exchange between models via an ontology-based data transformation script. Once the platform is established, the platform will be opened for extension by communities. |
