Abstract Some forming processes mainly consist in steady-state phases, and should preferably be modelled by steady state approaches to save computing time. However, some difficulties occur as the geometry of free surfaces is not fixed: the domain on which the computation is to be performed is not known a priori. An optimal control method for determination of these free surfaces is presented and its inclusion in a finite element code is described. Validation of the technique is made on a… CONTINUE READING
