Phase field modeling of fatigue fracture

This dataset contains Julia source code implementing a phase field method for simulating high-cycle fatigue fracture in materials. The code features an adaptive switching algorithm that alternates between Newton-Raphson and Modified Newton-Raphson solution schemes for computational efficiency. This implementation supports 2D single edge notched tension (SENT) specimens under displacement-controlled loading conditions. The code includes multiple fatigue degradation functions, strain decomposition strategies, and automatic crack tracking capabilities with VTK output for visualization.
