Abstract
The current work deals with the effects of metals behavior under inelastic deformation by using the optical methods of experimental mechanics: the DIC technique and infrared analysis. The subject of investigation is the inhomogeneity of the local strain rate fields and temperature bursts due to formation and propagation of localized plastic flow bands in uniaxial tension, and at the postcritical deformation stage. The main aim of the study is to estimate the loading conditions on the effects of serrated flow, on the mechanisms of the deformation bands initiation and the necking effects; to interrelate between local strain jumps and temperature bursts.
