The Effect of Transverse Shear Force on the Required Coefficient of Friction for Level Walking

Human Factors, 2011
Objective: An enhanced methodology to extract the required coefficient of friction (RCOF) value was used to investigate the effects of the transverse shear component of the ground reaction force (GRF) on the RCOF. Background: The RCOF is an important indicator for slip incidents. However, the extraction of the RCOF from GRF is not standardized.

Effects of Shear Stress Forces to Rotordynamic Coefficients in Staggered Labyrinth Seals

Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 2006
In this article, shear stresses in calculating the rotordynamic coefficients of staggered labyrinth seals are presented. Differences in the values of these coefficients are observed and quantified. The results of the present article are compared with the results of earlier formulations that neglect the effect of shear stresses for various geometries ...

Shear Elastic Coefficient of Normal and Fibrinogen-Deficient Clotting Plasma Obtained with a Sphere-Motion-Based Acoustic-Radiation-Force Approach

Ultrasound in Medicine & Biology, 2022
Blood coagulation is a process involving several chemical reactions governed by coagulation factors, during which the shear elastic coefficient, μ, varies as the medium transitions from liquid to gel phase. This work used ultrasound to measure μ during the clotting of human plasma samples by tracking the motion of a glass sphere located inside a ...

Distribution of drag force coefficient along a flexible riser undergoing VIV in sheared flow

Ocean Engineering, 2016
Abstract The drag force coefficients of a flexible riser undergoing vortex-induced vibration (VIV) in sheared flow are investigated for Reynolds numbers (Re) up to 1.2×105. Based on the drag forces theoretically calculated by the beam theory using the strains measured in a scale model test, the properties and distribution of the drag coefficients are

Modelling of dynamic cutting force coefficients and chatter stability dependent on shear angle oscillation

The International Journal of Advanced Manufacturing Technology, 2016
Productivity of high-speed turning operations is limited by the onset of self-excited vibrations known as chatter. Unless avoided, chatter vibrations may cause large dynamic loads damaging the machine spindle, cutting tool or workpiece and leave a poor surface finish behind.
