| Abstract Scope |
Hydrogen as a fuel is a promising alternative to traditional fossil fuels due to its abundance, high energy density, and clean energy profile. However, hydrogen can degrade the mechanical properties of metals, hindering its widespread use. We introduce a hydrogen-sensitive plasticity model as an important first step to understand damage behavior to enhance the viability of hydrogen fuels. This presentation will introduce constitutive equations for a crystal plasticity model that directly captures the plastic behavior of Ni201 which has been charged with varying hydrogen concentrations. The model is physically based on existing theories in the literature. Furthermore, the model's parameters are calibrated from multi-scale and multi-experiments, utilizing coupon-based and X-ray Diffraction Microscopy experimental data across different hydrogen concentrations. Finally, comparing the model results with the experiments helps support its validation as a step forward to understand and predict the behavior of Ni201 in the presence of hydrogen environments. |
