skin friction

[′skin ‚frik·shən]
(fluid mechanics)
A type of friction force which exists at the surface of a solid body immersed in a much larger volume of fluid which is in motion relative to the body.

skin friction

The frictional resistance developed between soil and a structure or between soil and a pile being driven in it.

A major proportion of the drag of streamlined vehicles and vehicles with large surface areas is due to the surface shear, so any reduction in the skin friction will produce more efficient vehicles by lowering fuel consumption and/or raising cruising speeds.
Both are currently developing computer simulations of the human hand to better understand grip strength, grip choice and skin friction in relation to 'openability' and 'squeezability' and the ease with which the elderly and disabled can access foodstuffs or medicines.
The key to prevention is to reduce heat and skin friction.
The problem with using concrete as a repair method in this type of scenario, however, is that contractors typically cannot get beyond the active zones in the soil and the downward pull of negative skin friction on the concrete piers, so they are not able to resist the soil's activity.

And of course we're always interested to see where the skin friction drag is high, and where it is low.
