Shear thinningWikipedia
In rheology shear thinning is the non-Newtonian behavior of fluids whose viscosity decreases under shear strain.It is sometimes considered synonymous for pseudoplastic behaviour and is usually defined as excluding time-dependent effects such as thixotropy. Shear thinning is the most common type of non-Newtonian behavior of fluids and is seen in many industrial and everyday applications.
