This research will conduct novel photoelasticity experiments by                 which local, normal and tangential stresses at the roll-work                    interface will be measured in the metal rolling process using the               birefringent properties of sapphire rolls.  The photoelastic                    investigation will provide the local coefficient of friction at                 the interface.  Realistic work materials such as steel, copper                  and aluminum will be rolled using the sapphire rolls.  The key                  focus will be to measure the interfacial friction coefficients                  using this technique.  These measured values will be compared                   with those computed using a finite element method utilizing                     measured interface velocities.  The longer range objective of                   this work is to develop a reliable analytical tool for rolling                  and similar forming processes and at the same time to gain a                    better understanding of the frictional conditions that are                      present in these processes.
