Experimental Measurement of the Drag Coefficient

Abstract

The drag coefficient is related to the dissipative viscous force which acts on a dislocation in motion. The magnitude of the drag coefficient for a dislocation of known Burgers vector is determined by measurement of the viscous force at a known dislocation velocity, or by measurement of the energy dissipation brought about by the viscous force. We discuss here these measurements and explore the special conditions which make possible the determination of the drag coefficient.
