Scalar Properties of Transversely Isotropic Tuff from Images of Orthoganol Cross Sections

Soil-Structure Interaction in Cross-Anisotropic Site Conditions

Tappan Zee Set for Inverset (Available only in Structures special issue)
Replacing the deck on New York's Tappan Zee Bridge is a ticklish problem, considering that all of the work has to be done at night. A combination of isotropically reinforced...

Implicit Integrations in Geoplasticity

Density-dependent Circulation in Desert-basin Aquifers with Isotropic Self-Similar Permeability Distributions
Closed-basin aquifers, typical of mountain chains in the western United States, present a central ephemeral lake (called `playa') where evaporation increases the local brine density creating...

Comparative Evaluation of Plasticity Theories Against Tension-Torsion Test at Finite Strain
This paper investigates and evaluates three hardening theories against a variety of nonproportional loading experiments on tubes made of annealed copper. It was concluded that the isotropic...

An Elasticity Solution for a Transversely Isotropic Material Containing a Spherical Shell Under Arbitrary Axisymmetric Loading
A three-dimensional elasticity solution is obtained for a transversely isotropic solid containing an isotropic spherical membrane shell. Perfect bonding is assumed between the shell and...

Structural Studies of Two Aerobrake Heatshield Panel Concepts
Structural sizing and performance data are presented for two different aerobrake hexagonal heatshield panel structural concepts. One concept features a sandwich construction with an aluminum...

Method of Analysis for Advanced Composite Structures

40Ar/³9Ar Laser Fusion and K-Ar Ages From Lathrop Wells, Nevada, and Cima, California: The Age of the Latest Volcanic Activity in the Yucca Mountain Area
K-Ar and 40Ar/39Ar ages from the Lathrop Wells volcanic center, Nevada, and from the Cima volcanic field,...

On Isotropic and Anisotropic Damage Variables in Continuum Damage Mechanics
The present work analyzes the implication and limitation of some 'scalar damage' models. In particular, the elastic-damage thermodynamic potential and the 'effective...

A Theory of Porous Plasticity at Low Triaxiality
A simple multiaxial theory of plasticity which is capable of taking into account the influence of pore shape at low concentration is developed for an isotropic porous material at a triaxiality...

Interlaminar Fracture Toughness Test: Traditional and Modified
For brittle, transversely isotropic, composite materials we have developed an alternative Mode II interlaminar fracture toughness test (GIIc) that...

Frictionless Contact of Composite Laminates
An approximate solution technique for determination of contact stress distribution under a curved, rigid punch indenting an arbitrary laminated composite plate is outlined. The individual...

Undrained Strength of NC Clay Under 3-D Conditions

Isotropic Fractionation During Air-Water Transfer of Oxygen and Nitrogen
We present empirical results that show the kinetic fractionation during gas exchange is 0.9972 ± .0002 for oxygen and 0.9987 ± .0001 for nitrogen. These values are larger than the solubility...

Rectangular Footing on Nonhomogeneous Elastic Half Space
The problem of a rectangular footing or a strip footing on a nonhomogeneous elastic half space is studied in this paper. The medium is assumed to be isotropic with a variable shear modulus...

Elastostatics

Hydrodynamic Dispersion: Estimation and Prediction
The dispersion of dissolved, nonreactive tracers in groundwater is governed by diffusion and advection. A.E. Scheidegger introduced the term dispersivity to describe the effect that a...
