Fractal features of fracture centers in heterogeneous materials revealed by discrete element method
The discrete element method has been used to explore the formation and evolution of fracture centers in heterogeneous materials under mechanical loading. It was found that these centers were formed near the surface of materials, and their fractal dimension was close to two. The growth of fracture ce...

| Summary: | The discrete element method has been used to explore the formation and evolution of fracture centers in heterogeneous materials under mechanical loading. It was found that these centers were formed near the surface of materials, and their fractal dimension was close to two. The growth of fracture centers leads to an increase in this fractal dimension.
The fractal dimension of broken bond centers (elementary acts of destruction) calculated for successive time intervals of 4096 events showed a significant decrease at the times of fracture center formation, which indicates the localization of the fracture process in the plane. |
