Effect of Elastic Anisotropy on Tunnel Wall Displacements Behind a Tunnel Face
The effect of elastic anisotropy (transverse isotropy) on the convergence behind a tunnel face is investigated by means of a parametric study. The applicability of existing expressions for evaluating the conv...

Applicability of existing models to predict the behavior of replicas of natural fractures of welded tuff under different boundary conditions
Assessing the shear behavior of intact rock and rock fractures is an important issue in the design of a potential nuclear waste repository at Yucca Mountain, Nevada. Cyclic direct shear experiments were conduc...

A 3-D boundary element formulation of viscoelastic media with gravity
This paper presents a boundary element formulation for 3-D linear and viscoelastic bodies subjected to the body force of gravity. The Laplace transformation is first used to suppress the time variable, and so...

Fracture mechanics analysis of cracked 2-D anisotropic media with a new formulation of the boundary element method
A new formulation of the boundary element method (BEM) is proposed in this paper to calculate stress intensity factors for cracked 2-D anisotropic materials. The most outstanding feature of this new approach i...

Application of the edge function method to rock mechanics problems
The edge function method is considered as an alternative to conventional numerical schemes for the solution of plane problems in rock mechanics. The essence of the approach is the approximation of the solution...

Stress concentration at irregular surfaces of anisotropic half-spaces
An analytical method is presented to derive the stresses in anisotropic half-spaces with smooth and irregular surface morphologies. The half spaces can be subjected to body forces, surface tractions, and unifo...

A Variational Formulation of The Boundary Element Method in Transient Poroelasticity
Poroelasticity is concerned with heterogeneous media consisting of an elastic solid skeleton saturated by a diffusing pore fluid. Its range of application covers a variety of important real-life problems, such...

On the state of stress in the near-surface of the earth's crust
Five models for near-surface crustal stresses induced by gravity and horizontal deformation and the influence of rock property contrasts, rock strength, and stress relaxation on these stresses are presented. T...

The influence of rock anisotropy on stress measurements by overcoring techniques
A medium is anisotropic if its properties vary with direction. This is the general characteristic of many rocks, for example, schists, slates, gneisses, phyllites and other metamorphic rocks. Bedded and regula...
