Diffraction Forces on Axisymmetric Bodies
Use of a Green function satisfying the governing differential equation and all boundary conditions except those on the boundary of the structure yields an integral equation, when these...
Approximate Solutions for Layered Foundations
A simple approximation to the dynamic response of foundations resting on layered soil profiles is presented. The approximation is based on an equivalent radiation damping which is numerically...
Boundary Zone Superposition Method for Linear and Nonlinear Dynamic Analysis of Infinite Domain Problems
The method is applicable to problems where input loads are imposed from within the finite element model or to problems where disturbances outside the finite element model generate input...
Soil-Structure Interaction in Seismic Environments
Soil-structure interaction depends on the mass, stiffness and the damping of the structure as well as on the geometry and embedment of the foundation and on the properties of the soil....
In Situ P and S Wave Velocity Measurement
A review of the in situ techniques to measure P and S wave velocities by seismic wave propagation is presented. A relatively new technique, the suspension PS logging method, is described...
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...

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...
Pile Creep Designs for Frozen Layered Profiles
A concept of relative creep stiffness suitable for the evaluation of the long-term, uniform creep behavior of non-ice type, frozen soils is presented. This concept extends the current...
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...
Behavior of Drilled Piers in Layered Soils on Texas Barrier Islands
Twenty-eight full scale load tests and the results of 41 geotechnical studies were analyzed to correlate shear strength interpreted from field and laboratory test data with those derived...
