Definitions for "Shear rate"
Measure of the rate at which a solder cream is disturbed, e.g. by stirring or other flow processes.
For MR devices in valve mode, shear rate is not constant across the gap. Peak shear rate is approximately equal to the average flow velocity divided by one fourth of the gap width. For MR devices in direct-shear mode, shear rate is the ratio of the shear velocity divided by the gap width.
rate at which adjacent layers of fluid move with respect to each other, usually expressed as reciprocal seconds.
Time required for breakdown of the shear strength.
