| Abstract: | This paper discusses some problems in the research of fractal fracture including the fractal characters of fracture surfaces and the measurement of their fractal dimensions, the relationship between fractal dimensions of fracture surfaces and macroscopic mechanical properties such as fracture toughness etc. , the fracture models and the fractal fracture mechanism. Furthermore, the prospects of performance of fractal theories on metal fracture are advanced in the paper. |
