Fracture processes occurring in particulate materials are paramount, especially when it comes to resource and construction industries. The thesis focuses on mechanical effects of internal rotations, which are essential for comprehensive understanding of mechanics of fracture propagation in such materials. A new rotational mechanism of fracture propagation is investigated, the pattern formation in the presence of internal rotations is characterised and the effect of negative stiffness on stability of and wave propagation in the materials with rotating non-spherical constituents under compression is studied. The thesis quantifies the effects of Internal rotations and develops the methods of their modelling and measurements.
