Investigation of the role of dislocation motion in the generation of acoustic emission from metal cutting

Abstract Due to the very high strain rates and temperatures encountered in metal cutting, opposing viscous damping forces are the dominant mechanism governing dislocation movement, which is the main mechanism for plastic deformation in metals. However, although viscous damping governs the physics of...
