For saturated soils, B = 1. For an elastic material, A = 1/3. For soils that compress under shear, A > 1/3, and for soils that dilate under shear, A < 1/3 Under the fully drained condition, the excess flowrow compose

"WebThen the shear rate is increased by a factor of 10 or greater (e.g. 1 or 10 1/s). At this high shear rate, the microstructure of the material is destroyed so the measured viscosity is lower.

Though the exact cause of shear thinning is not fully understood, it is widely regarded to be the effect of small structural changes within the fluid, such that microscale geometries within the fluid rearrange to facilitate shearing. In colloid systems, phase separation during flow leads to shear thinning. In polymer systems such as polymer melts and solutions, shear thinning is caused by the …
