On the application of finite-element techniques to problems concerning potential distribution and stress analysis in the earth sciences

摘要: The elastic response (i.e., displacement fields, strain and stress distributions) has been determined by structural matrix analysis for a homogeneous rock layer subjected to two-dimensional distributions of vertical applied along basal boundary. results obtained compare favorably with biharmonic function solutions bySanford [42]2) the authors. was then extended: effects different magnitudes superposed gravitationally-induced stresses, release constrained side boundary, introduction pronounced heterogeneity were each quantitatively evaluated. Each these changed conditions effected important alterations in characteristics, e.g., configuration trajectories, predicted locations configurations initial fracture surfaces, shear distributions, fields.
