The Perzyna Viscoplastic Model in Dynamic Behaviour of Magnetorheological Fluid under High Strain Rates

open access: yesEngineering Transactions, 2015
The extension of viscoplastic model of Perzyna for the field of magnetorheological materials is proposed. Perzyna’s approach is adopted to identify the mechanisms of microscopic rearrangement of ferroelements producing visible increase of material ...

An investigation of impact breakage of rocks using the split Hopkinson pressure bar [PDF]

open access: yes, 2015
Discrete element methods (DEM) are being used to provide detailed impact histories of the particles in comminution devices, such as mills. To match this immense detail of information, far more informative breakage tests than those that are generally ...
