Smart Strain Approximation Surface-Mounted Optical Fiber Strain Sensor
2020This study is aimed to develop a smart neural network perceptron model for strain prediction using fiber optic sensor signals. Optical parameters corresponding to surface-mounted optical fiber are obtained experimentally under static loading conditions.

Ordering of strained islands during surface growth
Physical Review E, 2010We study the morphological evolution of strained islands in growing crystal films by use of a continuum description including wetting, elasticity, and deposition. We report different nonlinear regimes following the elastic instability and tuned by the flux.

Simulation and Modeling of Nanoparticle Surface Strain
Journal of Nanoscience and Nanotechnology, 2012The effects of surface relaxation in the powder diffraction pattern from metal nanoparticles are discussed. Molecular dynamics simulations are carried out to simulate the structure of a series of free-standing Al and Cu nanoparticles of different sizes and stabilization temperatures.

Cell surface hydrophobicity of Klebsiella strains.
Archivum immunologiae et therapiae experimentalis, 1987On 14 encapsulated Klebsiella strains with different K-antigens and their non-encapsulated mutants the type of fimbriae present and the grade of hydrophobicity of their cell surface (expressed as SAT-value) were investigated. It could be demonstrated that clear correlations exist between the fimbriation of Klebsiella bacteria and their cell surface ...

Surface-mounted optical fiber strain sensor design
Applied Optics, 1991We develop the theory of surface-mounted interferometric optical fiber strain sensor design for arbitrarily configured fiber paths and present design techniques to select the path of a curved fiber-optic sensor required to isolate predetermined strain components. Several of these gauges are combined to form a rosette that directly measures the state of

Thermal apparent-strain sensitivity of surface-adhered, fiber-optic strain gauges
Applied Optics, 1992We have derived, based on established practice in experimental mechanics, an equation for calculating the thermal apparent-strain sensitivity of phase-modulated, surfaceadhered, adhered, fiber-optic strain sensors. This formulation permits the thermal performance of fiber-optic strain gauges to be compared with conventional resistive gauges.

Physical Review Letters, 2013
By combining density functional theory, nonequilibrium Green's function formulism and effective-Hamiltonian approaches, we demonstrate strain-engineered surface transport in Si(001), with the complete isolation of the Si surface states from the bulk bands.

Effect of strain on surface morphology in highly strained InGaAs films
Physical Review Letters, 1991The early stages of growth of highly strained ${\mathrm{In}}_{\mathit{x}}$${\mathrm{Ga}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$As on GaAs(100) have been investigated as a function of composition. The evolution of the film microstructure as determined by in situ STM and RHEED is from a two-dimensional rippled surface in the beginning stages of growth to ...

Photoelastic Measurement of Surface Strain
Aircraft Engineering and Aerospace Technology, 1960The investigations have been primarily concerned with some of the practical problems associated with the metoplastic technique, they have in this respect attempted to solve some of these problems with the best means available at the time.

Although some work exists relating to the kinematics of fluid surfaces, no development parallel to that for linear and volume elements exists. It is shown, in this paper, that a rate of surface-strain tensor can be defined that has the same relationship to rate of surface extension that the rate of strain tensor has to rate of linear extension.
