Public release of GRIPHFiTH Matlab library
We publicly released our “GRoup Implementation for PHase-field Fracture THeory” - GRIPHFiTH, a Matlab library to solve basic and advanced damage and fracture problems.
The code can be downloaded here.
The current version, stemming from the work of our Senior Assistant Pietro Carrara and of ETH Scientific IT Services (Mikolaj Rybinski and Gerhard Bräunlich), with contributions from our PhD student Francesco Vicentini, implements linear elasticity in 2D plane strain and the phase-field approach to fracture with:
- AT1 and AT2 models;
- volumetric-deviatoric, spectral and no-tension energy decompositions;
- irreversibility enforcement with history variable and penalty methods;
- staggered solution scheme.
New releases incorporating additional features will follow in the future.
