Failure Analysis of Masonry Structures
The use of smeared-crack and interface elements for the analysis of masonry structures is investigated. While a variety of structural problems can be solved with a combination of both...
Discrete Markov Process Approach to Fatigue Crack Growth
The discrete Markov approach considered herein is simple to implement and uses a two-dimensional stochastic model in conjunction with simulation to estimate model parameters. The possibility...
Random Response of Multicrystalline Structures
An approach to the probabilistic modelling and analysis of multicrystalline microfabricated beams is presented with application to micro-electro-mechanical systems (MEMS). Random, textured...
Pressure Losses Across Sequential Stenoses in Collapsible Tubing
The fluid dynamics of a model of a diseased artery with multiple stenoses were investigated in a recirculating steady-flow system over a range of Reynolds numbers (Re) from 30 to 1100....
Properties of Aggregate-Cement Interface for High Performance Concrete
An experimental study of the interfacial zone between aggregate and cement paste was undertaken. Various factors such as type of aggregate, treatment of aggregate surface, mixing process...
A Cumulative Failure Criterion of Concrete Under Uniaxial Dynamic Compressive Loading
It has been previously reported that the strength and critical strain of concrete under impact increase with strain rate, but neither of them can predict failure. A cumulative damage parameter...
The Generalized Brazier Problem for Orthotropic Straight Tubes of Finite Length
A new engineering approach, based upon a mixed variational functional, is presented for the analysis of the nonlinear static behavior of thin-walled, circular-cross-section cylindrical...
Crushing Response of Energy Absorbing Composite Structure
A description of why and how composite structures crush and absorb energy is presented. The three primary crushing modes of composite structure (transverse shearing, lamina bending and...
Reduced Basis Technique for Nonlinear Vibrations of Composite Panels
A reduced basis technique and a computational procedure are developed for the nonlinear free vibrations of composite panels. The computational procedure can be conveniently divided into...
Experimental Investigation of Bending and Twisting Coupling in Thin-Walled Composite Beams
The behavior of a thin-walled ppen section composite material beam depends on the anisotropic mechanical properties of the panels that form the beam. A beam theory has been proposed for...
A Discussion of the Numerical Modeling of Sea Ice Ridging
Pressure ridging, is the failure mechanism of the Arctic pack ice in compression. The large-scale compressive strength of the ice pack is determined by the aggregate of ridge building...
Erosion of Steep River Banks and Time Evolution Towards Equilibrium Channel Shape
A numerical analysis of the time evolution of straight river channels is presented. The bed and bank, material is taken to be coarse, non-cohesive and uniform in size. As a result of the...
Unconfined Granular Materials Thermalized by Fluctuating Horizontal Surfaces
We calculate the solid fraction and granular temperature throughout assemblies of identical, smooth, inelastic spheres that are unconfined from above and thermalized from below by bumpy,...
Integrity Testing of Concrete Elements Using Surface Waves
The Spectral Analysis of Surface Waves (SASW) method is a nondestructive testing procedure which has been extensively used to determine in situ the elastic moduli of soils and pavements...
Scattering of Waves by Steel Reinforcement in Concrete
The application of wave-sensing methods to the non-destructive evaluation of concrete structures requires often the use of simple (or at least tractable) models for the solution of the...
Finite/Macroelement Meshes in Neural Rat Growth
The well known attributes of neural rat growth during 7 to 14 days postnatally are used to demonstrate the decrease in calculated growth discontinuities with macro, as opposed to finite,...
Inverse Problems in Biomechanics
The FEM (Finite Element Method) is a powerful numerical technique in solving boundary value problems in Biomechanics, which are difficult to analyze by other closed form or numerical procedures...
Flexural and Shear Studies of Carbon Fiber Reinforced Beams
This paper presents the results of laboratory test on beams reinforced with three dimensional continuous carbon fiber grid. The grid is prefabricated by three-dimensional weaving and epoxy...
Compressive Strength and Characterization of Failure Modes for Polymer Concrete
The effect of aggregate type, polymer content and specimen dimensions on the compressive strength and failure modes of a polyester polymer concrete (PC) was investigated. Two aggregate...
Constitutive Modeling of Slurry Infiltrated Fiber Concrete (SIFCON)
Slurry Infiltrated Fiber CONcrete (SIFCON) is a unique material, containing 5 to 18 percent, by volume, of steel fibers; in contrast, standard Fiber Reinforced Concrete (FRC) usually contains...
