Accounting for shear deformation in fast models for plate rolling
Production Engineering, 2013For on-line prediction of roll force and torque, fast models have been available for a long time, which are mainly based on the slab method or other solution methods that allow for computing times in the range of seconds. Such fast models typically treat the rolling process as a plane strain problem and neglect shear deformation, which is always ...

Log-Rolling Micelles in Sheared Amphiphilic Thin Films
Physical Review Letters, 2005Using molecular dynamics simulations, we show that sheared solutions of cylindrical micelle-forming amphiphiles behave very differently under extreme confinement as compared to the bulk. When confined to ultrathin films, the self-assembled cylindrical micelles roll along the shearing direction and align parallel to each other with their axes along the ...

Mathematic model of rolling pressure during a semisolid shearing-rolling process
International Journal of Minerals, Metallurgy, and Materials, 2012A mathematic model of rolling pressure during a novel semisolid shearing-rolling process was established. The rolling pressure in this process is higher than that in the conventional rolling. The increment of rolling pressure in the backward slip zone is higher than that in the forward slip zone, and the neutral plane moves toward to the roll gap ...

Numerical Simulation Analysis of Influence Factors to Shearing Force of Rolling Shear
Journal of Iron and Steel Research International, 2011The calculation results show that relative cut-in depth at the moment of maximum shearing force decreases with the increase of steel plate thickness; along with blade clearance increasing, shearing force would increase slightly compared with the slide pressure of blade carrier; shearing force increases significantly with the increasing blunt end radius;

On Penetration of Shear Texture into the Rolled Aluminum and Copper
Metallurgical Transactions A, 1982The most important cause of the macroscopic inhomogeneity of texture is the nonuniformity of the penetration of the shear deformation through the thickness of the rolled metal. The authors have proposed a method making possible the observation of the penetration of shear texture from layer to layer.

Characterizing the Shear Deformation during Asymmetric Rolling
Materials Science Forum, 2008Asymmetric rolling has been considered as a possible way to obtain severe plastic deformation (SPD) since it will give an extra shear deformation to the processed materials during rolling. Previous researches have confirmed such a shear deformation.

Shear waves and grain-rolling in granular media.
The Journal of the Acoustical Society of America, 2009In a randomly packed unconsolidated granular medium, there is a random asymmetry in mechanical coupling between grains that has been shown to cause an increase in the effective inertia, hence a reduction in sound and shear wave speeds [N. P. Chotiros and M. J. Isakson, J. Acoust. Soc. Am., 121, EL70–EL76 (2007)]. The increase in inertia for shear waves

Mechanics of Cell Rolling Adhesion in Shear Flow
Advances in Bioengineering, 1997Abstract Leukocyte rolling along endothelial cells is a critical step of leukocyte-endothelium interaction, which plays important roles in tissue inflammation and wound healing [1]. The occurrence of rolling results from the dynamic balance of hemodynamic shearing force acting on the cell and adhesive bond force between cell and ...

Different roll regimes in shear-excited NLC
Journal of Applied Physics, 1978Two different stationary regimes for roll instabilities in homeotropically oriented samples of nematic liquid crystals are observed. The roll pattern can develop parallel or perpendicular to the applied shear depending on the frequency of the imposed stress.

The rheology and roll-to-roll processing of shear-thickening particle dispersions
2017There is a dynamic interaction between the immune, endocrine, and central nervous systems. The main function of the immune system is to protect the organism from pathogens by engaging a network of organs, cells and signaling molecules. Recently, the resident-immune cells of the brain have been found to be critical in supporting the full development of ...
