چکیده مقاله
Formation of dead metal zone in flat dies is an important issue in the direct extrusion process In the present work, using the improved velocity field and geometrical parameters of the dead metal zone curve, the required power of the extrusion process is determined Since the material tends to use minimum energy, with minimizing the upper bound energy, the geometrical parameters of dead metal zone profile are approximated This method does not depend on the exit section and is applicable to nonsymmetrical dies as well Analytical results for non symmetrical T die are in good agreement with the results of simulations of the finite element software ABAQUS 6 9
