The Reversible Bending of Turbine Shafts with Temperature

Proceedings of the Institution of Mechanical Engineers, 1955
The reversible bending of certain carbon-molybdenum steam turbine shafts is shown to be caused by expansion coefficient differences existing in the steel from which the shafts were made. This difference is a function of the heat treatment of the steel and it is shown that the magnitude required could be obtained in shafts of the size considered by ...

Reversible bidirectional bending of hydrogel-based bilayer actuators

Journal of Materials Chemistry B, 2017
Semi-IPN hydrogel-based bilayers were fabricated and exhibited unique bidirectional bending behavior in response to solution temperature and pH, which is vastly different from what is observed for bilayers composed of only conventional hydrogels.

Reversal of Secondary Flows in a Sharp Channel Bend

Coastal Engineering Journal, 2016
Field observations of the currents at a bending channel in the Abashiri River in Hokkaido, Japan have revealed an unexpected secondary circulation during flood tide with near-bed and near-surface c...

Low-Emittance Lattice Design with Reverse Bend and Longitudinal Gradient Bend for the PLS-III

Journal of the Korean Physical Society, 2020
With novel schemes using reverse bends and longitudinal gradient bends, the 4th generation low-emittance storage ring was designed for the Pohange Light Source-III: the upgrade of PLSII. A unit cell with one homogeneous bending magnet, designed by using a genetic algorithm, is commonly used in the design of multi-bend achromatic lattices to realize an ...

Design of a diffraction-limited storage ring lattice using longitudinal gradient bends and reverse bends

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2021
Abstract Diffraction-limited storage ring (DLSR) light sources are being developed towards the goal of reaching the diffraction-limited emittances. To reduce the emittances, multi-bend achromat (MBA) lattices with many bend unit cells are used in DLSR designs.

Enhancement in Elastic Bending Rigidity of Polymer Loaded Reverse Microemulsions

Langmuir, 2017
Elastic bending rigidity of the surfactant shell is a crucial parameter which determines the phase behavior and stability of microemulsion droplets. For water-in-oil reverse microemulsions stabilized by AOT (sodium 1,4-bis(2-ethylhexoxy)-1,4-dioxobutane-2-sulfonate) surfactant, the elastic bending rigidity is close to thermal energy at room temperature

Control of Reversible Self-Bending Behavior in Responsive Janus Microstrips

ACS Applied Materials & Interfaces, 2016
Here, we demonstrate a simple method to systematically control the responsive self-bending behavior of Janus hydrogel microstrips consisting of a polymeric bilayer with a high modulus contrast. The Janus hydrogel microstrips could be easily fabricated by a simple micromolding technique combined with an initiated chemical vapor deposition (iCVD) coating,

The role of bending stress on the initiation of reverse transverse defects

Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2020
This paper investigated the role of longitudinal reverse bending stress on the initiation of reverse transverse defects. The longitudinal reverse bending stress occurs due to the reverse bending of the rail between two-wheel passage leading to the generation of tensile bending stress at the railhead and the lower head areas.

Bending Dynamics and Directionality Reversal in Liquid Crystal Network Photoactuators

Macromolecules, 2008
We show how Bayesian statistics and density-functional theory can be combined to compute reliable values for the interactions in a cluster expansion for adsorbates on a surface. The method is an alternative to the leave-one-out cross-validation method.

Deformation Characteristics of Advanced High Strength Steel under Cyclic Bending and Reversed Bending

Key Engineering Materials, 2015
In the present study, the Bauschinger effect exhibited in the advanced high strength steel under cyclic bending and reversed bending deformation was examined by both the experimental approach and the finite element analysis. The cyclic tension-compression tests were first conducted for the DP590 steel sheet to determine the material constants required ...
