phase field approach to model ductile fracture
This animation shows the contours of the phase-field parameter for a flat notched bar, having low triaxiality and plane strain condition Lode equal to zero. The failure of the sample happens at the expected region, the central part of the sample as expected.
The phase-field implementation for modeling ductile fracture is available at the following link:
