ANALYSIS ON DEFORMATION BEHAVIOR FOR PURE COPPER PROCESSED THROUGH EQUAL CHANNEL ANGULAR PRESSING DIE
Keywords:
Equal Channel Angular Pressing, Deformation Behaviour , Flow BehaviourAbstract
Equal channel angular pressing (ECAP) is a feasible forming technique to process the material through a die without a change in cross sectional area of sample. The current work has been carried out to identify the deformation behavior of pure copper and its flow behavior along the die using ANSYS V12. The Analysis is carried out for different channel angles of 90˚, 110˚ and 120˚ for different hydrostatic pressure conditions. The results show that deformation along the die during pressing is inhomogeneous for various channel angles under different hydrostatic pressure conditions. Total displacement of sample during pressing decreases with increases with channel angle.
