On the Displaced Lattice Charge and Residual Resistivity

Canadian Journal of Physics, 1975
We have used the method of lattice statics to perform microscopic calculations of the displaced lattice charge far away from an impurity in an alkali metal. The displaced charge is then used to determine with the aid of the continuum approximation the change in solid structure factor and from it to estimate the correction to the residual resistivity ...

Study of displacement and residual displacement field of an interface crack by moire interferometry

Second International Conference on Photomechanics and Speckle Metrology: Speckle Techniques, Birefringence Methods, and Applications to Solid Mechanics; Moiré Techniques, Holographic Interferometry, Optical NDT, and Applications to Fluid Mechanics, 1991
Moire interferometry was used to study the deformation field and the residual deformation field around a crack laying along the interface of the adhesive layer and the adherend of graphite epoxy composite. Two steps of the experiment were carried on. First, the specimen was loaded in four levels and the fringe patterns are recorded for analyzing the in-

Determination of Maximum Residual Displacement from Velocimeter Records: Part 2. Methods and Results of Estimating Residual Displacement

Seismic Instruments, 2019
This is the second and final part of an article on determining maximum residual ground displacement from velocimeter records. Part 1 of the article considers methods for calibrating velocimeters; Part 2, methods for assessing and reconstructing velocimeter records of irreversible deformations occurring in the epicentral zone after destructive ...

Mechanisms of Residual Oil Displacement by Steam Injection

SPE Reservoir Engineering, 1987
SummaryIn an attempt to isolate various thermal and hydrodynamic mechanisms, a model of one-dimensional (1D) steam displacement of residual oil has been developed. The quasisteady model considers capillary pressure gradients and gravity forces during the simultaneous flow of oil, water, and steam to be the dominant factors in oil-bank mobilization.

Acute and residual neuromuscular effects of displacement in indirect vibratory stimulation

Journal of Electromyography and Kinesiology, 2021
The aim of this study was to evaluate the effect of indirect vibratory stimulation on different magnitudes of displacement on acute and residual neuromuscular responses. Fifteen healthy volunteers were randomly submitted to 3 experimental sessions, with intervals of 5 to 7 days (5 maximal voluntary contractions - MVC, 12 s of duration each and 5 min of

Probabilistic Characteristics of Residual Displacements of SDOF Systems

Applied Mechanics and Materials, 2013
Probabilistic residual displacement analysis plays an important role in determination of technical or economical feasibility of repairing the damaged emgineering structures after an earthquake. Probabilistic characteristics of residual displacements of SDOF systems were quantificationally investigated in this study through a comprehensive statistical ...

Residual displacement ratios for assessment of existing structures

Earthquake Engineering & Structural Dynamics, 2005
AbstractResults of an analytical study aimed at evaluating residual displacement ratios, Cr, which allow the estimation of residual displacement demands from maximum elastic displacement demands is presented. Residual displacement ratios were computed using response time‐history analyses of single‐degree‐of‐freedom systems having 6 levels of relative ...

Scaling of constant‐ductility residual displacement spectrum

Earthquake Engineering & Structural Dynamics, 2020
SummaryStructures undergoing inelastic displacements during earthquake ground motions are known to sustain some amount of residual displacements, which may make those unusable or unsafe. In this study an attempt is made to estimate residual displacements for elastic‐perfectly‐plastic single‐degree‐of‐freedom oscillators with a given ductility ratio ...
