Soil mechanics - Wikipedia

Soil mechanics, is a branch of soil physics and applied mechanics that describes the behavior of soils.It differs from fluid mechanics and solid mechanics in the sense that soils consist of a heterogeneous mixture of fluids (usually air and water) and particles (usually clay, silt, sand, and gravel) but soil may also contain organic solids and other matter.

Plastic Viscosity - an overview | ScienceDirect Topics

In evaluating drilling muds, it is common practice to report the effective viscosity at 600 rpm. This quantity is called the apparent viscosity, AV, and is given by (5.25)¯ AV = 300 × θ600 600 = θ600 2 Note that the term apparent viscosity is used by some authorities in a more general sense as an alternative for effective viscosity.
