Sentence examples for threshold friction from inspiring English sources

This paper investigates the impact of grid resolution, falling velocity of snow, turbulent Schmidt number, threshold friction velocity of snow and turbulence model on the CFD simulation results.

Further, a generalized process-based theoretical equation was derived to explain the decrease in threshold friction velocity in water-repellent soil for the case of soil particles modeled as asymmetrical cones.

We determined threshold wind speeds and corresponding threshold friction velocities to be 6.0 and 0.20 m s−1, respectively, for the 4 months immediately following the fire and 10 and 0.55 m s−1 for the following spring months.

Smaller a means higher sensitivity of slip velocity to the applied stress, which makes the behavior closer to the traditional strictly threshold-type friction.

Beyond this threshold value, increasing friction may adversely affect the energy dissipation and failure mechanism.

In general, the magnitude of the shift in the fatigue threshold in the friction stir welded coupons is a function of microstructure, residual stresses and specimen geometry.

However, the accuracy of the model is limited by imperfect identification of dust emissions, in particular by the friction velocity threshold parameterization in the emission process.

Detailed estimates of the uncertainty that propagates through the calculation based on the friction velocity thresholds (e.g. following Richardson and Hollinger 2007) was beyond the scope of this paper.

We adopt a frictional contact model in which slip is allowed wherever the shear stress along the interface reaches a threshold value defined as the friction strength.

Here (dot {gamma }^{alpha }) is the shear rate of the slip system α, similarly τ α is the shear stress, X α is the backstress and R α is the threshold stress, a component of friction that evolves with slip, of the same slip system.

Fatigue crack growth thresholds ΔKth were determined for friction stir welded butt joints made from aluminium alloys AA2024 and AA6013.
