Blending stiffness and strength disorder can stabilize fracture
Ehud D. Karpas, Ferenc Kun
Quasi-brittle behavior where macroscopic failure is preceded by stable damaging and intensive cracking activity is a desired feature of materials because it makes fracture predicta…
From fracture to fragmentation: discrete element modeling -- Complexity of crackling noise and fragmentation phenomena revealed by discrete element simulations
Humberto A. Carmona, Falk K. Wittel, Ferenc Kun
Discrete element modelling (DEM) is one of the most efficient computational approaches to the fracture processes of heterogeneous materials on mesoscopic scales. From the dynamics…
Mechanisms in Impact Fragmentation
Falk K. Wittel, Humberto A. Carmona, Ferenc Kun +1
The brittle fragmentation of spheres is studied numerically by a 3D Discrete Element Model. Large scale computer simulations are performed with models that consist of agglomerates…
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…
Universality behind Basquin's law of fatigue
F. Kun, H. A. Carmona, J. S. Andrade +1
One of the most important scaling laws of time dependent fracture is Basquin's law of fatigue, namely, that the lifetime of the system increases as a power law with decreasing exte…
Continuous Damage Fiber Bundle Model for Strongly Disordered Materials
F. Raischel, F. Kun, H. J. Herrmann
We present an extension of the continuous damage fiber bundle model to describe the gradual degradation of highly heterogeneous materials under an increasing external load. Breakin…
