Use of Hierarchical Lattices for Predicting the Fluid or Stress Transfer in Concrete
Hierarchical lattices are used to study the influence of local disorder on the transfer of properties (stresses, strains, permeability) from the micro-scale to the macro-scale. They are...

On the Diffusional Stress Transmission
A probabilistic diffusional mechanism for the propagation of intergranular forces has been formulated as a set of three mathematical assumptions. The equilibrium equations are complemented...

Nonlinear Behavior of Thin Slender Free Surface Non-Newtonian Elliptical Rings
This paper analyzes the nonlinear motion of a slender concentric thin elliptical ring of an incompressible, non-Newtonian fluid. This study includes the physical effects of surface tension,...

Refined Analysis of Load Distribution Factors for Bridges
This paper presents a new approach for calculating the distribution factors for slab-on-girder bridges. This method considers the coupling of longitudinal and transverse effects. The governing...

Experimental Photoelastic Analysis of Tunnels Containing Cracks

The objective of this study is to investigate the dynamic response of an infinite beam supported by a fluid on one side, and subjected to dynamic loading on the other side. The fluid underneath...

Computation of Wind Pressures on L-Shaped Buildings
The paper refers to the numerical simulation of turbulent wind conditions around an arbitrarily-shaped building composed of two rectangular blocks. The time-averaged Navier-Stokes equations...

Wind Effect on Oblique Motion of Two Bodies in a Uniform Flow
The wind effect on the general translational motion of a circular cylinder through an inviscid and incompressible fluid, conveyed by a uniform flow at infinity, in the vicinity of another...

Three-Dimensional Thermal Jump in Stratified Cooling Channel
This study is concerned with basic properties of three-dimensional thermal jumps. Temperature measurements obtained in three-dimensional thermal jumps are presented. The jumps analyzed...

Computation of Flow in Ice-Covered Dune-Bed Channels
A numerical method for solution of the Reynolds-averaged Navier-Stokes equations is developed to study the flow over sand dunes in two-dimensional channels. The method is applied to calculate...

Turbulence, and Energy Loss, at Combining Pipe Junctions
Efforts to measure and describe the loss of energy at 90? sharp-edged junctions are described. The work is focussed on energy losses at discharge and area ratios for which there are no...

Flow Visualization of Lid-Driven Cylindrical Cavity Flow
The lid-driven cylindrical cavity flows in the laminar region are quantitatively visualized by a new flow visualization method called the digital vector velocimetry method. Particle streak...

General Mechanism of Turbulence
By considering the vortex structures of turbulence and using the concept and theory of the pulsative convection and diffusion of instantaneous vorticity in a viscous fluid motion, the...

Wave Induced Vortex Near Seashore
The vortex motion behind submerged breakwaters in the nearshore region is studied. The RCPWAVE model (Ebersole et al., 1986) is used to calculate the wave field and thus the radiator stresses...

The Flow in the Front Stagnation Region of a Square Plate with a Small Disturbing Wire in its Upstream
The flow in the front stagnation region of a square plate was investigated experimentally in a water channel. A small wire was placed in the upstream of the square plate to create a small...

The Transverse Vortex in the Wall Regions of the Turbulent Boundary Layers in the Flows with Adverse Pressure Gradient
The vortical structures in the turbulent boundary layers in the flow with adverse pressure gradient were investigated by the hydrogen bubble technique. The vortices were visualized in...
