Popis:	Plastic instability associated with Luders band deformation affects the surface quality of structural steel products during metal forming operations such as drawing. In this work band growth mechanism involved in Luders deformation is studied in mild steel by analyzing deformation in two local zones within the Luders band width namely effective width and active zone using digital image correlation, an imaging, noninvasive technique for strain mapping. Change in magnitude of these local zones in the load plateau and associated strain rate variations within these zones clearly revealed the irregular growth of these zones reflecting the irregularity involved in two stage Luders band growth mechanism.
