摘 要:
This paper presents a new method to study the fractal feature of wood fractures implementing the 3D scanning technology. Abies holophylla and Populus alba were chosen as the materials. The results indicated that the 3D scanning technology could be used effectively in analyzing the fractal feature of wood fractures. It revealed a strong linear correlation between the cross section area of the wood fracture and the logarithm of its distance to the origin. Further,the study showed that the fractal dimensions on the fracture section between the highest point of the wood fracture and the cross section decreases gradually as the cross section moving to the bottom of the fracture. Finally statistically significant differences were discovered among different wood types in fractal dimensions of wood fractures. The mean fractal dimensions of Abies holophylla and Populus alba wood fracture were 2. 050 and 2. 091.
