The Importance of Discontinuities

Finite Element Analysis of Discontinuities in Concrete

A Fundamental Study on the Discontinuities and Heterogeneities of Asphalt Concrete

Finite-Element Analysis of Flexible Pavements with Discontinuities

Rock Structure in Relation to Concrete Dams on Granite
Granite is often considered to provide an excellent foundation for a concrete dam and a great many dams are thus founded on granitic rocks. Although granitic rocks lack the bedding of...

Discontinuities, Rock Deformation and Fluid Flow Around Emplacement Rooms
One of the major concerns for the design of the potential nuclear waste repository at Yucca Mountain is how to identify the fast flow paths and how to minimize the flow of the fast paths....

Performance Factors of Neutron Moisture Probes Related to Position of Source on Detector
The performances of two commercially available neutron moisture probes with different source-detector placement were evaluated. The probes were the Troxler with the neutron source placed...

Analysis of Internal Discontinuities in Geo-Materials
A new approach for modeling localized deformations is proposed. This approach uses an interface element to model the shear band. A successful capture of the kinematics of a failure mechanism...

Distributed Failure Analysis, Fallacies and Remedies
In the past, two distinctly different approaches - smeared and discrete failure descriptions have been utilised to capture failure mechanisms in solids and structures. These two approaches...

Finite/Macroelement Meshes in Neural Rat Growth
The well known attributes of neural rat growth during 7 to 14 days postnatally are used to demonstrate the decrease in calculated growth discontinuities with macro, as opposed to finite,...

Gradual Development of Bores in Canal Systems
Modern computer programs for modeling unsteady flow in open channels are typically constructed using a momentum conserving form of the Saint Venant equations. This allows computation of...

Isotopic Discontinuities in Ground Water Beneath Yucca Mountain, Nevada
Analytical data for stable isotopes in ground water from beneath Yucca Mountain, when examined in map view, show areal patterns of heterogeneity that can be interpreted in terms of mixing...

Models for Rock Mass Dynamics
The phenomenology of explosive effects in hard rocks is of interest to workers in the energy field, in the defense field, and in planetary science. The salient characteristic of hard rock...

Development of Density Discontinuities in a Turbulent Fluid

Location of Geologic Discontinuities by Geophysical Techniques
An overview of the seismic refraction method and resistivity methods is given. These two geophysical techniques are integrated into a systematic method for locating geologic discontinuities...

Convolution-Integral Modeling of Non-Equilibrium Sediment Transport
In transient process of sediment transport due to unsteady or/and nonuniform flow or discontinuity of boundary condition, non-equilibrium process appears and it sometimes plays an important...

Submerged Flow in Parshall Flumes
Recent data collected in a 1-foot Parshall flume located in the Bureau of Reclamation's hydraulic laboratory indicate a significant discontinuity in the discharge/submergence...

Real World Analysis
The structural concepts, seismic analysis and design of five recent highrise structures is presented in this paper. The paper deals with the problem of multistory buildings having Structural...

A Mesh Generator for the Modeling of Rock Discontinuities
The need to characterize a rock mass by collecting field data is receiving more and more emphasis as larger, more ambitious underground structures are being built. Yet there is a need...

Application of Displacement of Discontinuity Methods in Underground Mine Design
Displacement discontinuity methods for stress analysis, pioneered by Starfield and Crouch (see, for example, Starfield and Crouch, 1972; Crouch, 1976; and Crouch and Starfield, 1983),...
