Computational modeling of deformation bands in granular media. I. Geological and mathematical framework
Deformation bands Granular media
2015/7/1
Failure of granular media under natural and laboratory loading conditions involves a variety of micromechanical processes producing several geometrically, kinematically, and texturally distinct types ...
Geological and mathematical framework for failure modes in granular rock
Failure modes Deformation bands Shear bands Compaction bands Dilation bands Fracturing of sandstone
2015/7/1
We synthesize all the available data on failure processes in granular rock and provide a geological framework for the corresponding structures. We describe two categories: (1) sharp discontinuities ma...
