Study on the fragmentation of shells
Falk K. Wittel, Ferenc Kun, Hans J. Herrmann +1
Fragmentation can be observed in nature and in everyday life on a wide range of length scales and for all kinds of technical applications. Most studies on dynamic failure focus on…
Discrete Element Simulation of Transverse Cracking During the Pyrolysis of Carbon Fibre Reinforced Plastics to Carbon/Carbon Composites
Falk K. Wittel, Jan Schulte-Fischedick, Ferenc Kun +2
The fracture behavior of fiber-ceramics like C/C-SiC strongly depends on the initial damage arising during the production process. We study the transverse cracking of the 90° ply i…
Scaling behavior of fragment shapes
F. Kun, F. K. Wittel, H. J. Herrmann +2
We present an experimental and theoretical study of the shape of fragments generated by explosive and impact loading of closed shells. Based on high speed imaging, we have determin…
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…
