Integrated Finite Element Neural Network (IFENN) for Phase-Field Fracture with Minimal Input and Generalized Geometry-Load Handling
A single physics-informed CNN, trained on two load steps of one notched specimen, can replace the phase-field equation inside a FEM loop and reproduce crack propagation across several unseen geometries and load steps.
