Strain-Based Damage Deactivation in Concrete
Motivated by the 'mode I' microcrack opening and closing mechanism, a procedure for the deactivation of the damage is developed. Strain based projection operators are used to negate the...

Nonlinear Analysis of Strain-Softening Damage under Monotonic and Cyclic Loading
The paper reviews the modeling of damage by the microplane model and presents extensions required for cyclic loading. The general microplane constitutive model is implemented in a three-dimensional...

Automated Identification of Compression-Induced Cracking in Cement Paste
The development of image analysis techniques to identify cracks using scanning electron microscope images of hydrated cement paste is described. Cracks are identified based on both the...

Dugdale Model Applied to Crack Interactions
It is doubtful that modelling crack interactions problem within the context of elasticity adequately reflects the physical aspects as the failure of brittle material is approached. A model...

Contact Induced Damage
Contact induced damage is an important source of potential failure of engineering components. The particular applications where this damage occurs are in the automotive, aerospace and...

Complementary Potentials of Finite Elasticity
The principles of virtual displacements and forces are embodied in a functional P. The complementary potential P_c is defined by the equation; P_c...

Mechanics of Growing Deformable Solids: A Review
An attempt is undertaken to summarize the contemporary knowledge in mechanics of deformable solids of accruing mass. A general mathematical model of an abstract growing deformable solid...

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...

High-Resolution Interwell Seismic Experiments in Sedimentary Formations
High-frequency interwell seismic data were acquired to examine full waveforms recorded in the pulsed mode and in the swept mode as well as to perform traveltime inversion tomography for...

Estimating Damage and its Influence on Fracture Toughness
To estimate damage in a quantitative manner, a technique used whereby six values of linear strain are measured on a material element as a function of hydrostatic pressure. The high precision...

Resonant Column Testing of Dynamic Rock Properties
Critical parameters for geophysical wave propagation studies are the dynamic elastic properties (shear and Young's moduli, and Poisson's ratio) and the intrinsic material damping of rocks....

Effect of Water on the Consolidation of Crushed Rock Salt
The consolidation behavior of crushed rock salt, as the backfill in the under-ground disposal of nuclear waste, will be important in controlling room closure rates and local permeability....

A Wax-Coupled Borehole Seismic Detector for High-Resolution Measurements
A triaxial borehole seismic detector was developed for high-resolution measurements at frequencies up to 2,000 Hz. Applications for this detector include three-component shallow reverse...

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...

Ultrasonic Wave Scattering by a Crack in a Composite Plate
A hybrid method is presented for analyzing ultrasonic wave scattering of plane strain waves by a crack in a composite plate. The hybrid method combines a finite element formulation in...

Sensitivity of Lifeline Response to Models for the Spatial Incoherence of the Seismic Ground Motions
The sensitivity of the response of above-ground and buried lifelines to different models describing the spatial variability of the seismic ground motions is examined. It is shown that...

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...
