FORMABILITY OF SHEET-METAL UNDER LATERAL PRESSURE
… circular metal diaphragms to hydraulic pressure on one side. Also, the effects of using different die-shoulder radii on the bulge-forming process, bulge geometry, principal strains, membrane stresses, and formabil- ity are studied. A simple theoretical model is formulated and applied to …

An experimental investigation of sheet pile interlock behavior under lateral pressure
A series of lateral load tests were conducted on assemblies of four, 4 foot long U.S. Steel PS32 (regular strength) and PSX32 (high strength) straight web sheet pile sections. The instrumentation adopted in the testing program was geared toward monitoring the assembly displacements, load transfer …

Ultimate Strength of Clamped Steel-Elastomer Sandwich Panels under Combined In-plane Compression and Lateral Pressure
… panels under combined in-plane compression and lateral pressure. By using the Galerkin method and extending the semi-analytical method to clamped sandwich panels, the governing equations of sandwich panels have been solved by the Galerkin method. The material nonlinearity is treated by iteration …

Measurement of forces between and within bilayers of neutral phospholipids
… methods, osmotic, mechanical, and vapour pressures, were used to measure the work of removing water from lamellar phases composed of frozen dipalmitoylphosphatidylcholine ( DPPC ), melted DPPC, egg phosphatidylethanolamine or equimolar mixtures of DPPC and cholesterol ( DPPC/CHOL ), …

Molecular Dynamics Studies of the *Gating Mechanism of a Mechanosensitive Channel
… the gating can be explained by changes in the lateral pressure distribution within the membrane, molecular dynamics simulations of membranes mimicking the experimental conditions were performed. The lateral pressure profiles calculated from these simulations show how changes in membrane …

Structural efficiency study of composite wing rib structures
… combinations of axial compression, shear, and lateral pressure. The loading ranges considered are broad enough such that the designs presented may be applied to other stiffened panel applications. An assessment is made of laminate variations, increased spacing. and non-optimum geometric …

An analysis of Japanese foreign policy behavior : 1905-1941
… two central themes explored in the analysis are lateral pressure and status inconsistency. To illustrate the themes the study draws upon diplomatic history and social psychology. The study is an exploratory one which offers a theoretical not empirical analysis although some operational measures …

Vibration of stressed shells of double curvature
… ratio. Meridional edge restraints and internal lateral pressure reduce the wide variation of the natural frequencies in the negative curvature shells and in general raise the natural frequencies. External lateral pressure accentuates the reduction in natural frequencies of the negative curvature …

Piezoelectric Control of Structures Prone to Instabilities
… of axial compression and suddenly applied lateral pressure undergo large amplitude oscillations and may experience divergence. Under aerodynamic loading, they can experience flutter instability with the amplitudes of oscillations attaining a limit: LCO) or escalating without any limit. …

Elastic and inelastic analysis of panel collapse by stiffener buckling
… for analyzing the flexural-torsional and lateral-torsional buckling ("tripping") behavior of flanged stiffeners subjected to axial force, end moment, lateral pressure and any combination of these. The effects of cross-sectional distortion, postbuckling behavior of the plate (incorporated …

Validation of the ULSAP Closed-Form Method for Ultimate Strength Analysis of Cross-Stiffened Panels
… to the panels, and in some cases combined with lateral pressure. For eight of the panels full-scale experimental results are available, and these verified the accuracy of the ABAQUS results. The 67 ABAQUS results were then compared to the ultimate strength predictions from the computer program …

Theoretical studies of lipid-protein interactions in biological membranes
… and decreasing curvature of the protein. The lateral pressure is almost independent of protein size or concentration if expressed as a function of the bulk lipid density. The hard-core of the lipids is softened to a site-site Lennard-Jones potential. The particles are found to cluster within …

Solution of soil-structure interaction problems by coupled boundary element-finite element method
… differences in the computed shear stress and lateral pressures when the effects of the far field are considered. Results of the bearing capacity analyses of strip footing on elasto-plastic soils indicate that when the effects of the far field are taken into consideration, initial yield takes …

Wind-Induced Exchange in Semi-Enclosed Basins
<p>The wind-induced circulation over laterally varying bathymetry was investigated in homogeneous and in stratified systems using the three-dimensional Regional Ocean Model (ROMS). For homogeneous systems, the focus was to describe the influence of the earth's rotation on the lateral distribution …
