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...

Vortex Suppression in Wet-Pit Pump Intakes
Two distinct examples to suppress both air-entraining and boundary-attached subsurface vortices in large vertical pump intakes are presented that were developed by means of hydraulic model...

Functional Analysis in Continuum and Structural Mechanics
Following brief historical remarks, the equations of the hypercircle and hypersphere of Prager and Synge and associated formulae for pointwise bounds are derived. The application of the...

Steady-State Nonlinear Heat Transfer in Multilayered Composite Panels
A two-dimensional computational model is developed for the nonlinear heat transfer in multilayered composite panels. The model is based on a first-order thermal lamination theory with...

Probabilistic Assessment of Composite Structures
Formal procedures are described which are used to computationally simulate the probabilistic behavior of composite structures. The computational simulation starts with the uncertainties...

Nonlinear Geometric and Material Considerations in Shell Structures
A geometrically and materially nonlinear static shell theory allowing large displacements, rotations, and strains with parabolic shear is developed. The theory is cast into a total Lagrangian...

A Shear Locking Free Three-Node Triangular Plate Bending Element for Moderately-Thick and Thin Symmetrically Cross-Ply Laminated Plates
A shear locking free three-node triangular plate bending element based on Reissner/Mindlin theory for symmetric general cross-ply laminated plates is developed. The element has total nine...

First-Passage Failure Predictions for Yielding Primary-Secondary Systems
Approximate methods are used to investigate the effect of nonnormality (non-Gaussianity) on the time of first-passage failure for a linear secondary system mounted on a yielding primary...

First Order Importance Sampling Method and its Variance Reduction
This paper proposes an Importance Sampling method for structural system reliability problems with linearized modal failure surfaces. It has the advantage of locating all samples in the...

Response of Mono-Coupled Distributed Parameter Systems to Random Excitation
The random vibration of periodic structures consisting of a multiplicity of closely coupled distributed parameter substructures is addressed. The problem formulation is general, and the...

Interaction Between Soil and a Rigid Foundation in a Layered Medium: A New Analytical Approach
This paper is concerned with derivation of the impedance matrix for the problem of interaction between soil and an embedded rigid foundation in a layered medium. As an approximation, the...

Dynamic Response Analysis of Pile Foundations by Using Variational Calculus
Various approaches have been developed for the frequency-domain dynamic response analysis. The one proposed by M. Novak (1974) is simplest of all and yet produces the results very close...

Experimental and Theoretical Dynamic Compliances of Foundations
An experimental study of the dynamic behavior of surface foundations on granular soils by centrifuge modeling is presented. The test method allows a direct measurement of the complex-valued...

Similarity Solutions of Starting Jets and Starting Plumes
Similarity solutions of the starting jets and the starting plumes are obtained using a one dimensional model based on the top-hat profiles and the symmetry assumption for the velocity...

Slip Velocity and Temperature Jump in Flow over Rough Surface
The expressions for the slip velocity and the temperature jump are determined and used as the boundary conditions in the calculation of turbulent flow over rough surfaces. The slip velocity...

Shear Flow Between Walls in Relative Motion
The paper reports on experiments on Couette flow, i.e., the shear-induced flow between surfaces which are in motion relative to each other. The novel aspect of the work is the appearance...

Retrospect and Prospect: Micromechanics
In the mechanics community the term micromechanics is often used to identify scientific efforts in which certain overall macroscopic material response and failure modes are characterized...

Wave Propagation in Solids
The last fifty years have seen the development of a large number of application of the theory of wave propagation in solids to problems of interest to civil engineers. Most notable have...
