...X. P. Zhou; J. Bi; R. S. Deng; B. Li The principal objective of this work is to understand the effects of brittleness on crack behaviors in rock, rock-like materials, and the underlying fracturing mechanisms. Brittleness, as one of the critical parameters of rock, significantly affects mechanical...

.... The resulted macro-cracks of lithic arenite, greywacke, and subfeldspathic arenite are vertical cleavages, unordered discontinuous macro-cracks, and inclined macro-crack, respectively. The brittleness of lithic arenite, greywacke, and subfeldspathic arenite are 2.46, 3.54, and 2.61, respectively. The sandstone...

...DO Ehrenburg The behavior of brittle materials under biaxial and triaxial loading is predictable on the basis of stress envelopes derived from the properties of idealized materials. In the case of nonmetallic brittle materials, the idealized patterns must be somewhat modified to allow for the low...
