Abstract Scope |
Fracture surfaces of materials that fail in a brittle manner have been shown to be fractal. Crack branching patterns have also shown to be fractal. However, the two conditions are not the same. The fractal dimension of the fracture surface is independent of the strength and dependent on the fracture toughness. The crack branching pattern is a function of the strength. I will demonstrate that there is a relationship between the two situations of fractal character. George Quinn has been involved with identifying the crack branching patterns along with clarifying crack branching angles in the literature. I will show his contribution to understanding of the difference between fracture surface fractal dimension and the fractal character of crack branching. |
