Abstract
A process optimisation technique is proposed on the base of the combination of a numerical optimisation procedure and a finite element method. The optimisation algorithm is based on an augmented lagrangian method and is used to minimise an objective function subject to constraint functionals. This allows to adjust process parameters in the finite element model. The finite element method allows an accurate simulation of the process under consideration by taking exactly into account boundary conditions, applied loads and operating conditions. Furthermore, a sensitivity analysis is associated with this method in a consistent manner so as to assess accurately the gradient of the reponse function and the constraint functionals with respect to process parameters. An application to the control of springback during deep drawing of sheet metals is presented.
