Mechanisms of Deformation in Porous Rocks at the Grain Scale
This paper investigates two dominant pore-scale deformation mechanisms in porous rocks: crystal plasticity and micro-fracture generation. Modeling and simulation are conducted on the mesoscopic scale, defined as a scale smaller than the specimen but larger than the grain. Imperfections are introduced in the form of random voids and random crystal orientations. Depending on the imposed overall deformation, the overall stress response could vary dramatically with assumed pore-scale mechanisms.
