Journal ArticleDOI
Elastic Properties of Fractured Rock Masses With Frictional Properties and Power Law Fracture Size Distributions
TL;DR: In this paper, the authors derive the relationships that link the general elastic properties of rock masses to the geometrical properties of fracture networks, with a special emphasis to the case of frictional crack surfaces.
Journal ArticleDOI
Cross‐correlation between length and position in real fracture networks
TL;DR: In this article, the mean distance between a fracture center and its nearest neighbor is correlated to its length l such as d ∼ l0.3 and the average area around each fracture center within which no other fracture portion is lying has an ellipsoidal shape whose factor of anisotropy is correlated with l.
Journal ArticleDOI
Anomalous diffusion exponents in continuous two-dimensional multifractal media.
TL;DR: The mean anomalous and fracton dimensions, d(w) and d(s), are equal to those of homogeneous media showing that, on average, the key parameter is the fractal dimension of order 0 D0, equal to the Euclidean dimension and not to the correlation dimension D2.
Journal ArticleDOI
Anomalous kinetics in diffusion limited reactions linked to non-Gaussian concentration probability distribution function.
TL;DR: It is shown that the transition from mean field to anomalous reaction kinetics is intimately linked to the evolution of the concentration PDF from a Gaussian to non-Gaussian shape.
Journal ArticleDOI
Mechanics of the transition from localized to distributed fracturing in layered brittle–ductile systems
TL;DR: In this paper, a plane-strain 2D finite-element model is used to highlight the mechanical role of the brittle-ductile coupling in defining the patterns of fracturing, and an analytical approach is presented in order to estimate the maximum velocity along each fault permitted by both brittle and ductile media.
