Abstract
In the context of metal forming, optimization issues typically lead to inverse problems with a least‐squares minimization as the objective. Due to the nonlinearities in forming simulations, iterative optimization approaches have to be considered. Gradient‐based solution strategies for two inverse problems are proposed and compared to each other. Firstly, the identification of elasto‐plastic material parameters is regarded. Secondly, a recently developed approach for the determination of an optimal workpiece design is investigated. As a special feature, both approaches can be coupled in a non‐invasive fashion to arbitrary external finite element software via subroutines.
