Fracture of ice floes by percussion in a granular model

This repository contains files used and developed for the percussion and the fracture of an ice floe (viewed as mass-spring-damper system in 1D and in 2D), following the Griffith model. This repository was created for the purpose of a Master's level internship at the Jacques Louis-Lions Laboratory.

Structure

• docs contains useful information to understand the problem at hand. The most important files here are the two theses: Rabatel (2015), and Balasoiu (2020).
• reports contains weekly reports during the internship, and the final report.
• slides contains a presentation for the Master thesis defense.
• pdfs contains the PDF files (final report and slides) submitted for thesis defense.
• code contains the 1D and 2D code that was developed. To launch a 1D simulation, adjusts parameters and run the Python scripts Percussion1D-CLI.py and Fracture1D-CLI.py (this latter script also deals with Percussion). Jupyter notebooks are also available to test specific aspects of the problem.

Resources

All the classic scientific computing libraries (Numpy, Scipy, etc.) will have to be installed to run the scripts. Additionally, one might need:

• Bokeh for interactive plotting in Notebooks.
• PILImage for exporting simulation results as gifs.
