چکیده مقاله
In this paper, the stress and load relations in backward rod extrusion of lead have been obtained by the slab method for curved die profile By the use of a developed computer program, the optimum die profile has been obtained on the basis of minimization of stress and load in die workpiece contact surface By using the FEM software, ABAQUS, the optimum die angle for the conical die is also determined Then, the finite element and experimental load displacement curves have been determined It is illustrated that the extrusion load for optimum curved die is reduced by 11%, compared to that in the optimum conical die
