An Evaluation of Sediment Resuspension Parameterizations
The recent attention to managing surface water toxic substances has resulted in a number of modeling approaches, all of which to a great or lesser extent require accurate treatment of...

Application of the BEM to Elastodynamics in a Three Dimmensional Half Space
The boundary integral equations (BIEs) are formulated for scattering problems of elastic waves by a cavity or a crack in a three dimensional half space. Two formulations based on the Green's...

Explicit Integration of Boundary Integral Equations in the Frequency Domain for Wave Scattering Problems
The goals of this article are: (1) to present an efficient method for the integration of the boundary integral equations for wave scattering problems and (2) to apply this method to the...

A BEM-Perturbation Technique for Membrane Structures
Most of the previous work has concentrated on the free vibration problem. The present paper examines the problem of low frequency forced vibrations of a membrane due to an oscillatory,...

Nonlinear Quasi-Static and Transient Response Analysis of Shallow Shells: Formulations and Interior/Boundary Element Algorithms
Nonlinear integral equations are derived for the representation of displacements of shallow shells undergoing moderately large, quasi-static or dynamic deformations. A combined interior/boundary...

A Study on Non-Conforming Boundary Elements in Elastomechanics
This work is a critical study on the performance of non-conforming boundary elements in three-dimensional elastomechanics. The pervasive way of implementing the boundary element method...

3-D Flexible Embedded Machine Foundations by BEM and FEM
A study on the dynamic response of three-dimensional flexible massless foundations of arbitrary shape, embedded in a homogeneous, isotropic and linear elastic half-space and subjected...

Harmonic Vertical Pile Response in Non-Homogeneous Medium
This paper describes the application of the boundary element method to determine the steady state response of vertically loaded floating piles in a non-homogeneous medium in which the...

Vibration Isolation of Structures From Surface Waves in Layered Soil
This work deals with the problem of isolation of structures from ground transmitted surface waves generated by machine foundations. The isolation is accomplished by means of rectangular...

Three-Dimensional Boundary Element Techniques for Moving Boundary Problems
The boundary element method (BEM) is a powerful numerical method well suited for a wide variety of engineering problems. The numerical computations are performed only on the boundary of...

Recent Applications in Computational Mechanics
The papers in this book were presented at the sessions Applications of the Boundary Element Method to Structural Dynamics and Dynamic Response of Coupled Civil Engineering Structures at...

Negatively Buoyant Flow in a Diverging Channel
Negatively buoyant (plunging) flow from a horizontal, constant width channel into a diverging channel has been studied in the laboratory. The study was undertaken to provide information...

Intact Decommissioning Alternative for Nuclear Power Plants
Previous studies of decommissioning options for nuclear power plants have examined potential alternatives such as immediate dismantlement, entombment, and moth-balling. This paper describes...

Application of a Three-Dimensional Coupled Finite Element?Boundary Element Method
Three-dimensional conditions in underground construction occur at the face of a tunnel, at intersections of underground openings and around roughly equidimensional openings. As long as...

Simultaneous Withdrawal of Saline/Fresh Waters in a Stratified Aquifer
The objective of this study is to develop computational tools for simulating the flow behavior of an aquifer in response to simultaneous pumping of two stratified fluids from both sides...

Coastal Erosion Management in Australia and the U.S.
Current knowledge and management policies in both Australia and the U. S. favor non-structural over structural responses to coastal erosion problems wherever possible. The trend towards...

Modeling Boundary Layer Flow in Stormwater Detention Basins
An iterative procedure involving an implicit finite difference numerical scheme was implemented on an IBM personal computer for solving steady, uniform and nonuniform boundary layer flow...

Modeling Hydraulic Problems Using the CVBEM and the Microcomputer
The Complex Variable Boundary Element Method (CVBEM) offers an effective and efficient means for modeling two-dimensional potential and related flow problems. The method has been applied...

Boundary Shear Stress in a Meandering Channel
Longitudinal and transverse velocity, bed shear, and water surface elevation were studied in a fixed-bed, meandering, laboratory channel with naturally varying, non-prismatic cross sectional...

Three-Dimensional Simulation of Two-Fluid Movement in Porous Media Using the Boundary Element Method
The paper discusses three-dimensional problems that include a denser fluid overlain by water in an unconfined aquifer. The two fluid regions are bounded by two-dimensional surfaces, including...
