Polymodal faulting: Time for a new angle on shear failure
Conjugate, or bimodal, fault patterns dominate the geological literature on shear failure. Based on Anderson's (1905) application of the Mohr-Coulomb failure criterion, these patterns have been interpreted from all tectonic regimes, including normal, strike-slip and thrust (reverse) faulting. However, a fundamental limitation of the Mohr-Coulomb failure criterion e and others that assume faults...
متن کاملCompressive splitting failure of composites using modified shear lag theory
The shear lag model has been used in conjunction with the 3D elasticity equations to determine the stress state in a fiber/matrix system containing an interface crack. The use of a shear lag model to capture the stress state at the crack tip and the modelling of the region away from the crack tip by the elasticity equations leads to a simple analytical expression which can be used to determine ...
متن کاملFaulting of Rocks in a Three-Dimensional Stress Field by Micro-Anticracks
Nucleation and propagation of a shear fault is known to be the result of interaction and coalescence of many microcracks. Yet the character and rate of the microcracks' interactions, and their dependence on the three-dimensional stress state are poorly understood. Here we investigate formation of microcracks during sandstone faulting under 3D-polyaxial stress fields by analyzing multi-stationar...
متن کاملPossible Breakup of Dark Terrain on Ganymede by LargeScale Shear Faulting
A system of arcuate furrows in Galileo Regio and Marius Regio, two large blocks of ancient dark terrain, has previously been proposed to be the remnant of an originally more concentric furrow set that was disrupted by shear. Estimates of the two regions' poles of furrow concentricity indicate a considerable westward offset of the Galileo Regio pole. These measurements uggest he possibility of a...
متن کاملImpact compressive and bending behaviour of rocks accompanied by electromagnetic phenomena.
It is well known that electromagnetic phenomena are often observed preceding earthquakes. However, the mechanism by which these electromagnetic waves are generated during the fracture and deformation of rocks has not been fully identified. Therefore, in order to examine the relationship between the electromagnetic phenomena and the mechanical properties of rocks, uniaxial compression and three-...
