In the direct shear test simulation, 8 different test parameter groups are set up to explore the effects of basic particle adhesion, single particle porosity, rockfill porosity on shear strength and body strain and verify the correctness of the derived power law shear strength formula....
Finally, the per- meability of each sample could be calculated through the formula above. 2.3. Direct Shear Test Direct shear test on subballast was then performed in railway engineering laboratory of Beijing Jiaotong Univer- sity. The specimens used in this test had the same grading with ...
Shear stress is determined with the formula (3.2)τ=(6Qμ)/(wh2) where τ is shear stress, μ is fluid dynamic viscosity, Q is volumetric flow, w is chamber width, and h is chamber height. A variation of this chamber, called the Hele-Shaw chamber, is also in use (Usami et al.,...
2.6. Shear stress Human endothelial cells (1st passage) or murine lung endothelial cells (passages 5–7) were transferred to culture medium containing 2% fetal calf serum and either maintained under static conditions or exposed to shear stress (12 dyn cm−2) in a cone-plate viscosimeter...
As a result, circulating cationic liposomes will spend an increased residence time within this vessel, compared to larger DA or CV blood vessels, under reduced shear stress53,54. This, in turn, presumably increases the propensity of cationic liposomes to adhere to the anionic, heparan sulfated ...
149Citations Metrics Abstract In this work, we report a novel soft diffractive micro-optics, called ‘microscale kinoform phase-type lens (micro-KPL)’, which is fabricated by femtosecond laser direct writing (FsLDW) using bovine serum albumin (BSA) as building blocks and flexible polydimethylsil...

By the following formula, 𝛼α can be obtained: 𝛼=92·1−2𝜈𝑝1+𝜈𝑝.α=92·1−2νp1+νp. (9) For strain-rate dependency, the load curve defining the yield stress in uniaxial tension is replaced by a table definition, assuming dynamic test data are available. Thus, ...
The minimum diameter of the shaft Dshmin can be calculated as Dshmin = 1.72( Tmax ) 1 3 , τmax (26) where τmax and Tmax are the maximum of the shear stress and torque, respectively. 7.3 7.25 7.2 2.7 7.3 2.75 2.8 2.85 2.9 2.95 Stator pole arc angle[deg] (a) 32.5 32 31.5 31...
Given the shear stress multiple of the boundary layer as calculated above, it is clear that ionic diffusion driven by concentration gradients and linearly multiplied by shear rate at the catalyst surface is a further order of magnitude beyond typical cell electrolyte values. For these reasons, ...
