What is the minimum diameter wire that can be produced from a 5 mm initial diameter, annealed copper wire? (K=315 MPa; n=0.54)
• By simple stretching
• By drawing through a frictionless die, die angle = 10°, with no redundant work (ideal work only process model)
• By drawing through a frictionless die, die angle = 10°, assuming that the friction and redundant work contribute a total of 20% to the ideal work of deformation.
