Abstract (technical / expert description):

During the past decade, the technique
of Discrete Element Simulations
(DEM) made great progress and by now it is generally acknowledged as a
reliable tool for bulk solids description in a variety of applications.
There is a number of models available in the literature to
describe fragmentation of particles in DEM simulations,
however, by now the predictive power of these models is still poor,
especially when dealing with fragmentation probabilities and fragment
size distribution. Current approaches use purely spherical models and
there is still a gap in predictive fragmentation models for
non-spherical particles.

The aim of the present research project is to develop a particle model
which allows for both realistic modelling of fragmentation in DEM
simulations and at the same time highly efficient large scale
simulations.
