Phase field for brittle fracture implemented with the Trilinos Project.

In progress.

• Three-dimensional
• Dirichlet conditions on displacement only
• No Dirichlet conditions on phase field
• Staggered algorithm
• Anisotropic model of Miehe
• Homogeneous, heterogeneous or random heterogeneous media
• Linear tetra only
• Linearized elastic behavior, i.e., a single Newton-Raphson step is performed

Packages and libraries

• Built on top of Sandia's Trilinos Project [Website | Documentation | Mailing List | Packages | GitHub] and uses, for instance, the packages:

  • Epetra for linear algebra,
  • Amesos, AztecOO, Stratimikos for direct and iterative linear solvers,
  • Teuchos for parsing XML lists of parameters,
  • ML, IfPack for preconditioners.

• Additional required libraries: GMSH, METIS, Boost.
