Strain Distribution During Hot Rolling of Strip by Photoplastic Simulation

“…In a different approach to the problem several experimental attempts have been made to evaluate the three-dimensional strain distribution in hot-form ing processes using photoplastic techniques [22][23][24][25][26][27] . The approach is based on the permanent birefringence that remains locked into a photoplastic mate rial after large plastic deformation.…”
