### gcrack – Solver for Linear Elastic Fracture Mechanics

`gcrack` is a finite element solver for **linear elastic fracture mechanics**, developed during my postdoc at **ENSTA (IMSIA)**. It is built on [`fenicsx`](https://fenicsproject.org/) and features:
- Incremental crack propagation with indirect load control, ensuring each load step occurs precisely at the propagation threshold.
- Support for arbitrary anisotropic fracture properties, i.e., $G_c(\varphi)$.
- Basic support for heterogeneous media.
- A modular architecture for easy extension.

`fragma` is a **phase-field fracture solver**, also developed during my postdoc at **ENSTA (IMSIA)** and based on [`fenicsx`](https://fenicsproject.org/). Key features include:
- Indirect load control via path-following methods.
- Crack propagation in anisotropic media (work in progress).

### Ph.D. Thesis template
In collaboration with [Alexandre Daby-Seesaram](https://alexandredabyseesaram.github.io/), we made our Ph.D. thesis template openly available on GitHub: [https://github.com/floiseau/PhD_Thesis_Template](https://github.com/floiseau/PhD_Thesis_Template). If you encounter any issue, do not hesitate to report it to us using the GitHub issue tracker.

### Open-source dataset
During my Ph.D. thesis, I generated and made public a dataset of effective elasticity tensor obtained from discrete element simulations. This dataset is hosted in the RechercheDataGouv repository ([https://doi.org/10.57745/LYHM4W](https://doi.org/10.57745/LYHM4W)) and can be freely used for research.
