The script FEM_INTERFACE.jl contains the implementation of the quasi-static phase-field fracture model while main_tensile.jl contains the pre-processing and settings of the problem. The latter calls the functions of FEM_INTERFACE.jl.
The Geometries folder contains the finite element meshes and the files containing the boundary conditions used for the different configurations studied in the manuscript.
