Tool design optimization in steady-state extrusion processes, based on
the finite element discretization and nonlinear mathematical programming
techniques, is considered in this paper. In order to perform the optimization
the die geometry is adequately parameterized, according to the polynomial
representation. By imposing real technological and geometry constraints the
optimal tool design is effected by extremizing the actual optimization
objectives. In particular, the minimization of the forming energy consumption
and the maximization of the possible area reduction are considered. The results,
obtained numerically by assuming the Lagrange incremental elastic-plastic finite
element formulation in modelling the material flow and the considered
optimization approach, are compared to the known theoretical solutions, in cases
where such solutions are available. It is demonstrated that the discussed
approach is quite effective. [COBISS.SI-ID 2684443]
