Dynamic processes in tensile tests of SUS304 specimen were observed by dynamic ESPI that enables us to investigate the entire process of whole-field deformation. In later process of a plastic deformation state, we found that strain-localized band revealed by concentrated correlation fringes swept over the specimen repeatedly. Correspondingly, on the stress-strain curve, serrated variations took place. This phenomenon will be discussed associated strain-induced martensitic transformation.
