Granular mechanics teaching resources

This website contains teaching resources developed at SciGEM at The University of Sydney for teaching granular mechanics to undergraduate and postgraduate students.

There are a number of independent numerical tools, and where they exist already there are corresponding reference materials, worksheets and assessment tasks. If you use these materials in one of your classes, please let us know so that we can provide support

If you would like to see examples of these resources in operation, please check out the Gallery.
