Scaling of fracture systems in geological media

E. Bonnet, +6 more
- 01 Aug 2001 - 
TL;DR: In this paper, the authors provide guidelines for the accurate and practical estimation of exponents and fractal dimensions of natural fracture systems, including length, displacement and aperture power law exponents.

The role of acoustic emission in the study of rock fracture

David A. Lockner
- 01 Dec 1993 - 
TL;DR: A review of the successes and limitations of acoustic emission (AE) studies as applied to the fracture process in rock with emphasis on our ability to predict rock failure is presented in this paper.

Compression-induced microcrack growth in brittle solids: Axial splitting and shear failure

H. Horii, +1 more
- 10 Mar 1985 - 
TL;DR: In this paper, the elasticity boundary value problem associated with cracks growing from the tips of a model flaw is solved, and the variations of the "ultimate strength" and the orientation of the overall fault plane with confining pressure are estimated.

Flow properties of continental lithosphere

Neville L. Carter, +1 more
- 01 May 1987 - 
TL;DR: In this paper, it was shown that mechanically weak zones (σ 1 − σ 3 <10 MPa) at upper-, mid-and lower crustal depths, inferred from geological and geophysical observations and interpretations, is supported by empirically-determined steady-state flow properties of some common crystalline rocks.

Brittle Failure in Compression: Splitting, Faulting and Brittle-Ductile Transition

H. Horii, +1 more
- 16 Sep 1986 - 
TL;DR: In this paper, a simple two-dimensional mathematical model is proposed for the analysis of the brittle-ductile transition process, the corresponding elasticity boundary-value problem is formulated in terms of singular integral equations, the solution method is given, and numerical results are obtained and their physical implications are discussed.

Fracture of Brittle Solids

Brian R. Lawn
TL;DR: In this article, the authors present a unified continuum, microstructural and atomistic treatment of modern day fracture mechanics from a materials perspective, focusing on the basic elements of bonding and microstructure that govern the intrinsic toughness of ceramics.

The frequency-magnitude relation of microfracturing in rock and its relation to earthquakes

Christopher H. Scholz
- 01 Feb 1968 - 
TL;DR: In this paper, the frequency-magnitude relation of microfracture deformation was studied and the dependence of the parameter b on rock type, stress, and confining pressure was found to depend primarily on stress.

TL;DR: In this article, the Griffith Theory of Brittle Failure and the evolution of physical properties during brittle failure are discussed, including the role of pore fluid and friction and sliding phenomena.

Mechanics of discontinuous faults

Paul Segall, +1 more
- 10 Aug 1980 - 
TL;DR: In this paper, the authors derived a two-dimensional solution for any number of nonintersecting cracks arbitrarily located in a homogeneous elastic material, including the elastic interaction between cracks.

Development of stress-induced microcracks in Westerly Granite

Paul Tapponnier, +1 more
- 01 Apr 1976 - 
TL;DR: In this paper, the development of dilatant microcracks in stressed Westerly granite at 500 bars confining pressure, room temperature, was studied under the scanning electron microscope, showing that most cracks caused by laboratory-induced stress are long, straight and narrow, with sharp ends, in contrast to natural cavities, which are blunt, bridged and discontinuous.
