during the failure process. These studies conclude that joints fractal features play a dominant role in the mechanical behavior of rock joints. However, the in-situ and laboratory tests have limitations...J. Cent. South Univ. (2017) 24: 1619-1626 DOI: 10.1007/s11771-017-3567-9 Investigation on jointed rock strength based on fractal theory YANG Lan-lan(杨兰兰)1, 2, XU Wei-ya(徐卫亚)1, 2, MENG Qing-xiang(孟庆......
fractal features with machined metal surface [10], a general mathematic method is proposed for synthesis of Weierstrass-Mandelbrot (W-M) fractal representation and parametric surface in 3D space... with parametric profiles It is well recognized that the rough surfaces on machined parts exhibit fractal features. However, most current researches are focused on the fractal measurement......
]. The fractal dimensions of various features of a porous medium can be determined experimentally, such as mercury intrusion curves[8-9] and water retention curves[10]. However, the most popular method... Fractal analysis of granular ore media based on computed tomography image processing WU Ai-xiang(吴爱祥)1, 2, YANG Bao-hua(杨保华)1, 3, ZHOU Xu(周 旭)1 1.

(2020) 27: 3013-3024 DOI: https://doi.org/10.1007/s11771-020-4525-5 Calculating changes in fractal dimension of surface cracks to quantify how the dynamic loading rate affects...) and digital image correlation (DIC) techniques are combined to analyze the dynamic compressive failure process of coal samples, and the box fractal dimension is used to quantitatively analyze......
to similar microstructural features and fracture behaviors. In this study, the results confirm this relationship. The higher fracture toughness of ATC composites corresponds to a higher fractal dimension...

was investigated by electrochemical noise(EN), SEM and EDX. Fractal theory was primarily used to depict the corrosion process of the alloy. The fast wavelet transform(FWT), as well as the fast Fourier...; the second stage involves the growth of a passive oxide layer; and the third stage involves reactivation. With increasing immersion time, fractal dimension increases fast initially, fluctuates......
Fractal in Fatigue Fractography杨京俊,周向阳,柯伟摘 要:<正> Fracture profile roughnesses and fractal dimensionsof fracture traces were measured on a fatigued Ti-6Al-4Valloy.It is found that although fractal dimension can wellreflect the variation of fracture traces with the measuringunits,it is difficult to apply it to quantitative analysis offractured......
