Cavity Expansion in a Dilatant Geological Material

New Models for Rock Joints and Interfaces
Two new developments and refinements in the modeling of rock structures are presented: a new model for axisymmetric interfaces, such as found in footing designs, and a new model which...

Dilation Angle and Liquefaction Potential
It is proposed herein that the dilation angle or expansion rate of the sand during shear is such a measurement. It can readily be obtained in the laboratory from drained triaxial or simple...

Shear Dilatancy in Rock and Precursory Changes in Seismic Velocities

Shearing Flows of Granular Materials
We study the shearing flow behavior of granular materials, using a theory based on one proposed by Goodman and Cowin in 1971. Solutions to the equations of motion are presented for the...

Plastic-Fracturing Theory for Concrete
Incremental plasticity and fracturing (microcracking) material theory are combined to obtain a nonlinear triaxial constitutive relation that is incrementally linear. The theory combines...

Threshold of Dilation under Cyclic Loading
The lower threshold of cyclic stress or strain that can be sustained in a soil without a tendency for permanent volume change is an important criterion in many foundation problems. However,...

Pore Pressures Near Moving Underwater Slope
Pore pressures near a moving boundary of a saturated soil mass are calculated and compared with tests. For a more realistic approximation of the stress-strain behavior of soil, a dilatancy...

Finite Element for Buckling of Curved Beams and Shells with Shear
Inclusion of shear deformations allows the bending theory to be extended to relatively thick beams and shells and, at the same time, simplifies the finite element formulation for both...

Analysis of Moderately Thick Shells of Revolution
Using plausible transverse distributions of stress and a functional distinction between the differential transverse shears, a new method is presented for analysis of moderately thick arbitrary...

Characteristics of Turbulent Boundary Shear Stress
The results of limited measurements of the instantaneous boundary shear stress in smooth boundary, free surface flows are presented. A commercially available, flush surface, hot-film sensor...

Structural Analysis of Flexible Airfield Pavements
The elastic moduli of pavement materials of conventional flexible airfield pavements are evaluated based on behavior pattern inherent in the CBR equation. This is based on the principle...

Pierced Shear Walls of Stepwise Variable Thickness
The continuous connection technique is now established as a quick and accurate method for the analysis of uniform pierced shear walls, which are commonly used as the primary structural...

Hydrodynamical Stability of Salt Wedge
The hydrodynamical stability of a salt wedge is examined in terms of a simple example consisting of two layers of fluids in uniform shear. The upper fluid is lighter than the lower fluid...

Short Wave Models with Fixed Bed Boundary Layer
The required scale relationships for wave models with fixed bed are developed using dimensional analysis, and reviewed in the light of recent research. Special emphasis is placed on modeling...
