Mixed-Field Finite-Element Computations
… for the propagating modes in waveguides via the finite-element method. The variational form of the Direct method is derived to ensure that an extremum is reached. The Direct method uses Maxwell's equations directly, both zero and first-order, scalar and vector bases that are used in the …

Immersed and Discontinuous Finite Element Methods
… elliptic problems and construct optimal immersed finite element approximations and discontinuous immersed finite element methods for the Stokes interface problem. In the first part we present an error analysis for the minimal dissipation local discontinuous Galerkin method applied to a model …

Finite Element Analysis of Nonlinear Consolidation
A general finite element method of solving nonlinear consolidation is presented for the unified treatment of saturated and partially saturated soils. Two sources of nonlinear material behavior are identified. The nonlinear material behavior under fully drained condition is represented by an …

Finite element analysis of groundwater contamination
… of this study was to develop a computational Finite Element model, validated by experimentation, to assist in the understanding of groundwater contamination problems. It was mainly aimed at studying the extent and manner of travel of contaminants in the saturated soil of unconfined aquifers …

A Unified Overlapping Finite Element Formulation
The use of finite element analysis has now become ubiquitous in engineering practice. However, obtaining an adequate mesh for a geometrically complex analysis domain is still challenging in traditional finite element analysis since the elements can be severely geometrically distorted and thus …

Finite element simulation of electrorheological fluids
Electrorheological (ER) fluids change their flow properties dramatically when an electric field is applied. These fluids are usually composed of dispersions of polarizable particles in an insulating base fluid or composed of liquid crystal polymer. To build more suitable and complicated designs for …

Finite Element Analysis of Geotextile Tubes
… behavior of geotextile tubes is studied using finite element modeling. Two initial shapes are investigated, one with a flat length-to-width ratio of 2:1 and the other with a flat length-to-width ratio of 5:1. The tubes are modeled resting on elastic foundations. For each initial shape, the …

Finite Element Analysis of Ship Collisions
… to obtain, and model testing is very costly. Finite Element Analysis (FEA) provides an alternative to physical validation that can be used to increase confidence and insight in simplified model results. This thesis develops a complete methodology for ship-to-ship collision simulations using …

Display of finite element beam stresses
… a computer program for graphically displaying finite element beam stresses is discussed. Beam elements are represented as thick lines with colored stress contours along the length. Stress gradients through the beam thickness are not displayed. Many program options are available to aid in …

Finite Element Analysis of Deep Excavations
… dissertation describes enhancements made to the finite element program, SAGE, and research on the performance of deep excavations. SAGE was developed at Virginia Tech for analysis of soil-structure interaction problems (Morrison, 1995). The purpose of the work described in this text with SAGE was …
