| Abstract: | The progress of fractal theory on materials science has been reviewed and the signifi- cances of fractals on materials mechanical behaviors has been pointed out.It states several measurement methods of fractal dimensions on the fractured surfaces of materials.Furthermore,it cites the examples to point out the fractal characteristics of the fractured surfaces in rocks and the relationship between the fracture toughness and the fracral dimension. |
