Paper presented at the 51st U.S. Rock Mechanics/Geomechanics Symposium, June 25–28, 2017
Paper Number: ARMA-2017-0138
.... Digital Image Correlation was further employed to calculate the strain field developed by change in sample structure in order to investigate the likelihood of micro-fracture development. From the results of this study, it was found that a) the sample exposed to 0.2M NaCl solution experienced the most...

... the same conformal unstructured mesh. The network of natural fractures is represented explicitly in the mesh. The behavior of the fractured medium due to changes in the fluid pressure, stress, and strain fields is investigated. The methodology is validated using simple cases for which analytical...

Paper Number: ARMA-2012-593
... which the stress and strain fields around a flaw tip were analyzed using the finite element code, ABAQUS, to better understand the processes involved in crack initiation and propagation. Double-flaw geometries were modeled with ABAQUS with the intent of identifying the differences between stress and...

.... Where groundwater resources are disrupted by longwall mining, the effect may be quantified in terms of changes in the conductivity and connectivity of aquifers overlying the mined panel (Bai ? Elsworth, 1994). The mining-induced strain field dilates or compresses pre-existing fractures that comprise the...

... predictive model. To circumvent this problem, an analytical method using the Fourier complex variation principle is proposed to predict the supplemental strain field caused by mining. It allows the definition of the general area of strata failure under a variety of mining and geological conditions. 2...
