Abaqus Code for a Residual Control Staggered Solution Scheme for the Phase-Field Modeling of Brittle and Ductile Fracture

Abaqus UEL and UMAT subroutines for the phase-field modelling of brittle and ductile fracture. The code consists of the 3-layered system including the user elements and user material subroutine producing a staggered algorithm with a residual norm-based stopping criterion.

The finite element formulations include 4-node full integration 2D and 8-node full integration 3D linear elements.

The source code and input files for the examples published in the associated journal paper as well as the PhD thesis are provided here. The files contain detailed explanations and instructions for users.

This is an updated version of the dataset!
Ductile material behavior has been included with 2 different phase-field formulations, more examples with better explanations, python scripts etc.
For simplicity, the brittle examples are included with elastic material model only. In future versions, complete generalization of the model will be provided.
