Abstract

Full-field strain distributions in the cold drawing of polycarbonate cylindrical bars are obtained using photoplasticity at three stages of neck propagation. The results indicate that the radial and circumferential strains are almost identical. The strain distributions in the seemingly straight (drawn) portion are nonuiform. The locations of maximum and minimum strains shift when elongations increase. Various sensitivity studies are also reported.
