dc.description.abstractSelection of processing and geometrical parameters is a crucial step in the extrusion process design. Optimized parameters may result in desirable microstructure at minimum load. To achieve this goal, dynamic material modeling (DMM) and genetic algorithms (GA) are used in this study. Selection of strain rate and temperature is done by DMM which insures dynamic recrystalization (DRX) zone during processing. Minimization of punch load is formulated as a nonlinear programming problem which is solved using GA to result in optimum ram velocity and die angle. Two rod extrusion processes are successfully optimized using proposed approach.en_US
