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...

Evolution of Damage in Brazilian Test Using Holographic Interferometry
A common method for estimating the tensile strength of concrete is the Brazilian Test. The test is carried out by loading a cylinder on its side in diametral compression. Accodring to...

Wave Propagation in a Nonlocal Strain-Softening Continuum
The problem of wave propagation in a nonlocal strain softening solid is first discussed analytically. It is demonstrated that 'loading' waves can still propagate in the strain softening...

On the Role of Dispersive Waves in Strain-Softening Media
Wave propagation in strain-softening continua is investigated numerically and analytically. It is argued that localisation which typically acts as a precursor of failure, can only be described...

An Evaluation Study of Modified Mohr-Coulomb and Cap Models
Two failure criteria, namely Mohr-Coulomb and cap models, are considered in this paper with some modifications. Mohr-Coulomb theory is applied to concrete after stress and strain cut-offs...

Micromechanics Based Design for Pseudo Strain-Hardening in Cementitious Composites
Micromechanical model constructed on the basis of fracture mechanics and fiber bridging provides a means of selection of fiber, matrix and interface property combinations for which short...

Stochastic Mixed Finite Difference Method
Some aspects of numerical solutions of stochastic mechanics problems are considered. The Finite Difference method for discretization of stochastic continuous media problems is discussed....

Mechanical Properties of High Performance Concretes
This paper presents some of the initial results of a 4-year research project on mechanical properties of high performance concretes with particular reference to highway applications. High...

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,...

Form Comparison Without Anatomical Landmarks
The mathematical basis for various morphometric interpolating techniques is discussed. A technique, which enables analysis of biological forms without homologous anatomical landmarks,...

Modeling Bond Stress-Slip of Reinforcing Bars Embedded in SIFCON
A brief description is given of the mechanisms associated with the bond shear stress versus slip response of deformed reinforcing bars embedded in slurry infiltrated fiber concrete (SIFCON)....

Experimental, Physical and Numerical Modeling of Lunar Regolith and Lunar Regolith Structures
An extensive series of laboratory strength and deformation experiments have been performed on a lunar regloith simulant. Results of these experiments are compared to results from experiments...

Measuring Vibration in an Advanced Composite Beam with Localized Internal Fiber-Optic Strain Sensors
Two optical fibers embedded with different configurations were used separately as strain sensors to measure the natural frequencies and modal amplitudes of a cantilevered graphite/bismaleimide...

Shear Zone Formation and Slope Stability Analysis

Discontinuous Deformation Slope Stability Analyses

Response Variability and Reliability of Plates Using the Weighted Integral Method
A methodology is introduced to perform both the response variability and reliability analysis of two-dimensional stochastic systems (specifically plates subjected to plane stress or plane...

Serviceability Analysis of Wood Beams with Creep
The effect of creep deformations on the serviceability reliability of single, dimension lumber wood beams is examined. A viscoelastic stress-strain relationship is used to model the time-dependent...
