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.
