Two-Dimensional Analysis of Water-Filled Geomembrane Tubes Used as Temporary Flood-Fighting Devices
… assumed to be infinitely long, and it is modeled two-dimensionally. Beam elements are used to model the tube. The tube is inflated with water. The hydrostatic pressure in the tube is converted to point loads and applied at the beam nodes in the direction perpendicular to the chord connecting two …

Two Dimensional Analysis of Vibration Isolation of Rigid Bar Supported by Buckled or Pre-bent Struts
… in this research. The three cases studied are 1) two buckled struts supporting a symmetric rigid bar, 2) two buckled struts supporting an asymmetric rigid bar, and 3) two pairs of buckled struts with a bonded filler supporting a symmetric rigid bar. The models are subjected to a harmonic …

Two-Dimensional Analysis of Four Types of Water-Filled Geomembrane Tubes as Temporary Flood-Fighting Devices
Two-dimensional analysis of four types of water-filled tube dams is carried out: an apron-tube dam, a single baffle tube dam, a sleeved tube dam, and a stacked tube dam. Since the analysis of the water-filled tube dam involves highly nonlinear geometric deformations and interactions with soil, …

Thermal properties of structural details in wood frame homes : analysis and recommendations
… 150 years ago. This study centers around the analysis of the thermal properties of structural details in light wood frame homes, focusing on wall construction details for both retrofit and new construction. A two dimensional analysis software, THERM 5.2, is used to perform finite element heat …

The applicability and accuracy of computer modeling in regards to acoustical scattering by a complex geometry
… is not uniform in section, a fact which means a two dimensional analysis of scattering will not suffice. Instead, the distribution of reflected sound waves over a hemispherical shell will be examined.

Analysis of the vibrations of inflatable dams under overflow conditions
A two-dimensional analysis is applied to the vibrations of inflatable dams under overflow conditions. The static analysis yields the equilibrium state for both the free surface profile and the shape of the dam. The dynamic analysis investigates the small vibrations of the inflatable dam about the …

Analysis and design of composite curved frames
In this work, methods for rapid analysis and design of composite curved C-section frames subjected to axial tensile loading are developed. Failure is predicted using polynomial in-plane and interlaminar failure criteria. Interlaminar stresses can be directly computed only from three-dimensional …

The Effects of Basin Slope and Boundary Friction on the Character and Plunge Location of Hyperpycnal Flows Entering a Laterally Unbounded Basin
… The plunging of high density flows in two dimensional channels has been extensively studied before. A fundamental assumption in these studies is that the flow is laterally confined. These studies allow the flow to plunge only in two directions, the horizontal x-direction and the …
