Thermal deformation behavior of Mg–3Sn–1Mn alloy based on constitutive relation model and artificial neural network

open access: yesJournal of Materials Research and Technology, 2023
The flow stress behavior of Mg–3Sn–1Mn alloy during thermal compression deformation was systematically studied. The thermal compression simulation experiment was carried out at different deformation temperatures and different strain rates in the range of

Heat conduction in deformable Frenkel-Kontorova lattices: thermal conductivity and negative differential thermal resistance

open access: yes, 2011
Heat conduction through the Frenkel-Kontorova (FK) lattices is numerically investigated in the presence of a deformable substrate potential. It is found that the deformation of the substrate potential has a strong influence on heat conduction.

Quantum limits to estimation of photon deformation

open access: yes, 2014
We address potential deviations of radiation field from the bosonic behaviour and employ local quantum estimation theory to evaluate the ultimate bounds to precision in the estimation of these deviations using quantum-limited measurements on optical ...

Numerical investigations on thermal deformation of large deployable reflector in space during earth eclipse (2nd report, investigations to suppress thermal deformation by internal force control)

open access: yesNihon Kikai Gakkai ronbunshu, 2016
Space structures encounter various severe environments in space. One of these environments is severe thermal condition where the difference of temperature during day-time and night-time is about 200 degrees Celsius. During this eclipse time, the midpoint

Study of Influence of Laser Cutting Sequence upon Thermal Deformation of a Base Sheet

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2007
In case that a lot of products were cut out from a wide base sheet by laser cutting, the sheet had been much deformed so that the error occurred in a height regulator. This paper deals with thermal deformation of a base sheet caused by laser cutting.

Thermally-induced responses of triaxially woven fabric composites

open access: yesHeliyon, 2023
The article examines the thermal responses of one-ply triaxially woven fabric composites (TWFCs). A temperature change experimental observation is first conducted on plate and slender strip specimens of TWFCs. Computational simulations are then performed

Cooled Pads for Tilting-Pad Journal Bearings

open access: yesLubricants, 2019
Tilting-pad journal bearings (TPJBs) are widely installed in rotating machines owing to their high stability, but some drawbacks can be noted, such as higher cost with respect to cylindrical journal bearings and thermal issues.

The lower bound violation of shear viscosity to entropy ratio due to logarithmic correction in STU model

open access: yes, 2017
In this paper, we analyze the effects of thermal fluctuations on a STU black hole. We observe that these thermal fluctuations can affect the stability of a STU black hole.
