En route to a multi-model scheme for clinker comminution with chemical grinding aids
R. K. Mishra, D. Geissbuhler, H. A. Carmona +7
We present a multi-model simulation approach, targeted at understanding the behavior of comminution and the effect of grinding aids (GAs) in industrial cement mills. On the atomist…
Fragmentation processes in two-phase materials
Humberto A. Carmona, Anderson V. Guimarães, José S. Andrade Junior +3
We investigate the fragmentation process of solid materials with crystalline and amorphous phases using the discrete element method. Damage initiates inside spherical samples above…
Packing of elastic wires in spherical cavities
N. Stoop, J. Najafi, F. K. Wittel +2
We investigate the morphologies and maximum packing density of thin wires packed into spherical cavities. Using simulations and experiments, we find that ordered as well as disorde…
Fragmentation processes in impact of spheres
H. A. Carmona, F. K. Wittel, F. Kun +1
We study the brittle fragmentation of spheres by using a three-dimensional Discrete Element Model. Large scale computer simulations are performed with a model that consists of aggl…
Break-up of shells under explosion and impact
F. K. Wittel, F. Kun, H. J. Herrmann +1
A theoretical and experimental study of the fragmentation of closed thin shells made of a disordered brittle material is presented. Experiments were performed on brown and white he…
Fragmentation of shells
Falk Wittel, Ferenc Kun, Hans J. Herrman +1
We present a theoretical and experimental study of the fragmentation of closed thin shells made of a disordered brittle material. Experiments were performed on brown and white hen…
