Computer simulation of fracturing of layered rock

Engineering Geology, 1971
Abstract Fracturing of rocks is simulated using an electronic computer, on the assumption that when a stress acts on a model, the fracturing condition is determined according to Mohr's theory and that of Griffith. A rock body is regarded as an aggregate of a grid cell whose strength is expressed by a random number of Gaussian distribution functions ...

Stresses in rock outside buckled layers

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1979
Abstract The author presents a theory of folding stresses in rocks, based on assumption of elastic equilibrium or slow viscous flow and a known fold geometry. The theory was first formulated in 1960–1961 and applied in practical problems. At this stage the general form of the solution is derived, applicable to arbitrary fold configurations.

Ambiguity of elasticity measurements in layered rocks

SEG Technical Program Expanded Abstracts 2007, 2007
Different boundary conditions applied to finite-size, heterogeneous rocks result in different average or apparent elastic stiffnesses. In statics, the apparent stiffness tensors that correspond to the homogeneous stress and homogeneous strain boundary conditions provide the lower and upper bounds for the true or effective stiffness tensor.

Fracture Behaviour of Layered Rocks with Alternating Stiff and Soft Layers

2022
Various subsurface engineering activities, including the stimulation of unconventional hydrocarbon reservoirs, the development of geothermal energy and the drilling and blasting operations, have been increasingly carried out in sedimentary rocks with layering structures.
