| Abstract Scope |
Extreme fusion environments can drive cracking, deformation, and surface degradation in plasma-facing materials, making rapid materials qualification a major challenge for fusion energy systems. To address this need, we are developing an AI-enabled digital-twin framework that connects high heat-flux testing, physics-based fracture simulations, and microstructure-sensitive machine learning for tungsten-based plasma-facing materials. The framework uses electron-beam exposure data from the JUDITH facility at Julich as the experimental foundation, while CabanaPD peridynamics simulations provide complementary damage fields for interpreting crack evolution and expanding the accessible response space. These learned structure-damage linkages support surrogate models capable of predicting degradation trends under fusion-relevant thermal loading. Supported by the DOE Genesis Mission, this work advances a foundation for autonomous damage assessment and materials optimization, with future applicability to real-time evaluation workflows in emerging facilities such as the Materials Plasma Exposure eXperiment at Oak Ridge National Laboratory.
