A Data-Driven Method for Modeling Creep-Fatigue Stress-Strain Behavior Using Neural ODEs
Neural ODE models trained on 19 experimental creep-fatigue tests of Alloy 617 reproduce stress-strain loops better than the standard Chaboche model, and symbolic regression converts one into an interpretable polynomial.
