Julia constitutive model integration
A Julia translation of the codes used to perform single material point integration and linear stability analyses in the Cosserat Breakage Mechanics paper, which were originally a mix of Python and Mathematica. As Julia is still a fast-evolving language, and I wrote this repository before becoming aware of the principles of good code replicability, I cannot guarantee that the suite will work out-of-the-box, although if it doesn’t, it shouldn’t be too far away, and I am happy to help in making it work for anyone interested in using it for science.

Data sets
On the Moreau–Jean scheme with the Frémond impact law: energy conservation and dissipation properties for elastodynamics with contact, impact and friction
The data set accompanying the paper (and codes) of the same name. This includes the input meshes used in the finite element analyses, the outputs of the simulations in Python pickles and .vtk files, and certain large images used to demonstrate the mesh (which are used as inputs in some of the plotting codes contained in the codebase).
