Causation-guided mechanism identification and interpretable reduced-order modeling of damage-driving grain-boundary stress in creep
Weichen Kong, Yanwei Dai, Yinglin Zhang +2
GB local stress is central to the initiation and evolution of long-term creep damage in polycrystalline superalloys. Owing to the high-dimensional nonlinear relationships between t…

A dual-scale stochastic analysis framework for creep failure considering microstructural randomness
Weichen Kong, Yanwei Dai, Xiang Zhang +1
Creep failure under high temperatures is a complex multiscale and multi-mechanism issue involving inherent microstructural randomness. To investigate the effect of microstructures…
